Biology
Human Body
1. Human body is made up of very small blocks called cells. These contain a living substance called Protoplasm.
Systems of the Body
2. Skeletal system – The frame of the human body is made up of bones. It consists of 206 bones. It helps the body to stand, give shape to the body and also protects the inner organs like brain, heart etc. It also gives attachment to muscles. In the bone mellow RBCs are produced.
3. Muscular System – Comprises the flesh pieces under the skin. There are two types of muscles.
i. Voluntary muscles – which we can control.
ii. Involuntary muscles – which we cannot control. Eg. Cardiac muscles.
4. Digestive System – Comprises of 28 feet long tube. It helps in the digestion of food, produces blood and provides heat and energy to the body.
i. Mouth – Food is chewed in the mouth and here it mixes with saliva. Saliva is a fluid that comes to mouth from three pairs of salivary glands. It converts starch into sugar.
ii. Stomach – is a pouch made up of fine hair like projections. Here gastric glands coverts proteins into peptones.
iii. Small intestine – It is 22 feet long tube. Its secretion change starch into sugar and proteins into peptones. Thus a major part of the digestion process is completed in the small intestine.
iv. Large intestine – It segregates water from the food.
v. Liver – works as a store house for carbohydrates, minerals and vitamins. It helps to keep sugar level of the body constant.
5. Circulatory System – Digestive system helps in the formation of blood. Respiratory system purifies the blood while circulatory system circulates the blood to the different parts of the body. Impure blood from all parts of the body comes to heart which works like a pumping station. Heart pours the impure blood into lungs. Purified blood is again brought to heart to be distributed to all parts of the body. The vessels that take pure blood from heart are called Arteries and the vessels that take impure blood to the heart are called Veins.
6. Respiratory System – helps us to breath air in to lungs. Here oxygen combines with hemoglobin and is thus distributed to all the limbs.
7. Excretory System – Consists of lungs, skin and kidney. The lungs throw out waste matter of the body in the form of carbon dioxide. Kidneys are two been shaped organs on either side of the spinal cord. When blood flows through kidneys they strain out poisonous material which along with water is passed on to the urinary bladder. Skin throws out waste material in the form of sweat. Skin gives a sense of touch and protects inner organs and give shape and colour to the body.
8. Nervous system – Nervous system consists of brain and spinal chord. The brain controls the memory and other processes of the body.
9. Bladders – There are 2 bladders in the human body.
i. Gallbladder – Stores and produces Bile. Bile is a green coloured fluid. Bile is later poured into the small intestine and helps in removing poison from the blood.
ii. Urinary Bladder – collects waste material filtered out by kidneys and passes it down by two tubes called urethras.
10. Thyroid Gland is situated on the base of the neck. It controls the speed of the various body processes.
11. Pituitary Gland is situated near brain. It is also known as Master Gland. It controls other glands and determines the height of the individual.
12. Liver is the largest gland in the human body. It stores extra sugar in blood and releases sugar when it is required by the body. It manufactures urea and secretes bile.
13. Lungs – their main function is to purify blood with the help of inhaled oxygen.
14. Pancreas produces pancreatic juices and insulin which helps in burning carbohydrates. The deficiency of insulin causes diabetes.
15. Spleen – is the blush red organ situated left to the stomach. It is the birth place of WBCs and grave yard for RBCs. During fever and other infections spleen is enlarged and protects body by killing germs.
Blood
1. Blood is a red coloured fluid in the body which consists of RBCs, WBCs and Plasma.

108. Which reading on both Centigrade and Fahrenheit thermometer is same - -40o C
109. Why does a body immunized in water weighs less – due to the upward thrust of water.
110. What keeps the glider up in the air – The upward thrust of air.
111. What controls the direction of the aircraft – tail unit of the craft.
112. Why motorists use convex mirror – its focal length is long so it gives a wider field of view. It gives virtual, erect and diminished image.
113. How is it that a needle sinks in water but a ship does not – ship displaces water which weighs more than its own weight (Archimedes principle)
114. Water preserved in a porous vessel is cooler, why – loss of heat i.e., latent heat of water in evaporation.
115. How does fish live in river where water is frozen – water has maximum density at 4oC and ice is formed at 0oC. The formation of ice starts at top while under the surface the temp. is 4oC. So fish can live.
116. Why do two eyes give better vision then one – It gives a three dimensional picture.
117. Why is the moon devoid of atmosphere – Moon’s thinness is 10-13 of the earth which causes low gravity. So gases emanating from the surface escape into inter planetary vacuum.
118. Why do clothes keep up warm during winter – Clothes prevent the heat of the body from escaping
119. In high mountain region bleeding through nose occurs because the pressure of blood in capillaries is higher than outsider pressure.
120. What is convection – It is the transfer of heat through a liquid or gas by the actual movement of atoms or molecules.
121. Why does ice float in water but sink in alcohol – Ice has less specific gravity than that of water but more than that of alcohol.
122. The burns produced by steam are deeper than those caused by boiling water as the same temp. why – Steam has more latent heat than what the water has a the same temp.
123. Why do we not feel the movement of the earth – because we are also moving at the same temp.
124. Why is mercury used in thermometers – It is a good conductor of heat and expands uniformally on heating.
125. Why is kerosene poured on stagnant water. – Kerosene being lighter than water, floats over the water and forms a film. It does not allow the air of the atmosphere to enter the water and help the mosquitoes to breed. (stops the supply of O2)
126. How is an electrical current carried from one place to another – It travels by flow of electrons through conductors.
127. A drop of water or mercury on a clean glass plate is circular in shape – why – surface tension in the case of a liquid drop is greater which makes its surface area minimum.(area of a spherical body is minimum.
128. Why does a train stops when chain is pulled – As soon as chain is pulled vacuum breaks and air rushes and brakes are applied.
129. Why does a red flower look red – It absorb all other colours of light except red colour.
130. Why is a compass used as an indicator of direction – The magnetic needle of a compass always lies in N-S direction under the influence of earth’s magnetic field..
131. Why does radio reaction improve after sunset – After sun set there are no ionizing radiations from the sun and so ionosphere which reflects radio wavers becomes more sable. This improves radio reception.
132. Why does the gun kick back when a bullet is fired - \to every action three is an equal and opposite reaction – Newton’s third law of motion.
133. Sun appears red during sunrise and sunset because light rays from the sun have to travel a longer distance since red colour has the longest wave length it is scattered in the atmosphere.
134. Why does a cyclist bend while taking a curved turn – He bends in order to make the centre of gravity remain within the base. This saves him form falling.
135. Why does a coin lying at a the bottom of a tall cylinder full of water seem to be raised. – Rays coming out from the coin bend outward due to refraction.
136. Why do diamonds shine at night – On account to high refractive index, the rays of light get totally internally reflected.
137. Why are we advised to empty our fountain pens before boarding a plane – Atmospheric pressure at higher altitudes is less than the pressure inside the pen so ink flows out due to lower pressure.
138. Why does a man lean forward while climbing a hill – A man leans forward so as to keep him in a stable equilibrium. Leaving increase the base of support so that the vertical line passing through the centre of gravity may fall with its base.
139. If we cross the atmospheric limits of the earth there is no atmosphere and scattering of light does not take place and sky appears black.
140. What is photosynthesis? - is a process in which plants prepare carbohydrates (their food). During day time in the presence of chlorophyll while consuming carbon dioxide and water. During this process they release oxygen. During night time since photosynthesis process stops and respiration continues plants liberate carbon dioxide. So it is not advisable to sleep under a tree at night.

The revolt was completed suppressed by the end of 1858. Rani Laxmi Bai died fighting and Bahadur Shah was exiled to Rangoon as a prisoner. The main causes of failure of revolt were:
i. lack of proper leadership
ii. The British had better arms and resources.
iii. Natives rulers and educated Indian class did not participate.
General History
1. The Portuguese were the first among Europeans to establish direct trade links with India.
2. Vascodegama, a Portuguese traveler reached Calicut in 1498 via Cape of Good Hope.
3. The Dutch formed several trading companies by the end of 16th Century.
4. The French trade was established in 1664.
5. In 1600, the British company was granted permission by Queen Elizabeth II to trade with India.
6. The British East India company was set up in 1600.
7. In 1608 the first vessel reached India at Surat.
8. British setup their first factory at Surat in 1612
9. In 1698 a new company was established know as East India Company.
10. In the earlier 18th century they got trading rights in territory of Bengal, Hyderabad, Gujarat etc. from the Mugal Empire Farookh Siyar.
11. Subsidary Alliance system was introduced by Loard Wellesley. Under this system the British made a subsidiary army in the territory of its ally and in turn took a part of his territory.
12. Doctrin of Lapse was introduced by Lord Dalhousie. Under this he assisted the territory of State which did not have a legal heir.
13. Regulating Act was passed by the British Government in 1773. The Governor of Bengal was made Governor General of India Warrenhasting became the 1st Governor General of India.
14. Pitts India Act was passed in 1784 to remove the shortcomings of Regulatory Act for the first time.
15. The Permanent Settlement of Bengal was introduced by Lord Cornwallis in 1793. It was a revenue system which the zamindars were converted into landlords.
Revolt of 1857
The Revolt of 1857 is also know as the first freedom national movement.
1. Political causes – Lord Wellesley’s subsidiary Alliance System succeeded in expanding the East India Company’s dominance through subjugation of Indian States so that they finally lost their independence. In addition many states were annexed by the Britishers under the Doctrine of Lapse introduced by Lord Dalhousie. He also refused to recognize titles of ex-rulers. The imperial Mughal glory suffered at the hands of company rule. In 1849 it was decided that the Mughal successors to Bhadurshah would have to shift from Red Fort to the outskirts of Delhi.
2. Economic Cause – The economic policies of the British in India completely destroyed India’s traditional economic fabric. The country was turned into a colonial economy serving the needs of the rulers mother country. The availability of cheaper machine made goods hit the handicraft sector, which could not compete in foreign markets because of higher import duties. India was forced to export raw materials on the thus domestic industries suffered as they had to purchase raw material at high prices.
3. Administrative Cause – The companies administrative machinery was not only inefficient but also prejudice against the Indian’s. Police and the judicial systems were racist. Indians were denied key positions in civil and military and they were rarely promoted.
4. Military Causes – The Indian sepoys were as displeased with alien rule as the people at large. The sepoys were denied all that they once enjoyed. The Post Office Act of 1854 withdrew even the free postage facility for them. The Indian sepoys considered inferior and treated badly. Could neither get paid properly nor easily avail of promotions.
5. Social and Religious Causes – Social discrimination of the British against the Indians and the missionaries attempted to spread Christianity in India. Convinced the Indian mind that the countries religion and culture would be violated. In social life the British treated the natives as inferiors. Despite being guilty of criminal assault on Indians the whites were acquitted with little punishment. Attempts by the English to end sati, child marriage and infanticide was suspiciously viewed and legislation of widow remarriage and introduction of western education antagonized the traditional Indian society.
Q. What was the immediate cause of the Revolt? Also describe briefly the revolt?
Ans. The Revolt of 1857 which is also considered as the first war of independence against British rule covered a significant area from Punjab in the North to Narmada in the South and from Bihar in the East to Rajputana in the West. However the focal points were Delhi, Kanpur, Lucknow, Baraily, Banaras, Jhansi, Meerut and Arrah.
The hanging of Mangal Pandey a soldier from Baragpur in March 1857 sparked a small revolt.
The immediate provocation was the use of greased cartridges. In May 1857 soldiers of the 3rd native cavalry at Meerut refused to use the Enfield riffle issued by the British. The riffles required to be refilled by biting off the top paper with the mouth. Rumor had it that the cartridge were smeared with cow and pig fat.
Spread of Revolt – The sepoys of Meerut in open rebellion marched to Delhi where the local infantry joined them. Many Britishers were captured some were killed also. At Delhi Bhadur Shah was declared the titular head of the ocuntry.
General Bakt khan from Baraley Regiment Captured Delhi. The revolt at Lucknow was led by Begum Hazrat Mahal of Awadh. At Kanpur Nana Sahib proclaimed himself the peshwan. He was supported by his rebel Lieutenant Tantya Tope and also by Assem Ulha. In Jhansi the revolting troops proclaimed Rani Lakshmi Bai the widow of Ganga Dhar Rao as the ruler. She also received the support from the troops of Sindias of Gwalior.
Q. Describe the causes for failure of revolt of 1857.
Ans. Through the revolt was a brave effort, it was doomed to fail owing to many weaknesses. The Revolt was a localised affair concentrated in portions of North India. Even from this area many rulers and chiefs did not participate. In fact, the educated upper and middle classes were critical of the mutiny.
The British formed a consulted programme to suppress the 1857 mutiny which through patriotic lacked a definite ideology. There was no central leader behind the revolt.
Compared to the superior weaponry and strategy of the British the war fare technique of the sepoys were out moded. The sepoys had a limited number of guns and fought mainly with swords, spears and these like.
Q. What was the impact of the revolt ?
And. The Indian Administration was placed directly under the crown by Government of India Act 1858. The East India Compny no longer required to manage the affairs inIndia, thus ending dualism. As per the act in Britain a Secretary of State for India was to be appointed who would be assisted by 15 member advisory council.
2. Recognising the role of the Indian states in the revolt it was decided ot preserve them as the bulwark of the empire. The Queen’s proclamation promised to discontinue the practice of annexation. The people were assured of religious freedom.
3. As the Indian army had begun the mutiny of 1857 the British made attempts to strengthen the military administration. European troops were increased in number. Most of the Indian artillery units were disbandoned and all effective weapons placed in European hands. All important posts were for the English alone.
4. Another significant decision was to involve Indians in legislation os that the rulers would be acquainted with the feeling and demands and misunderstandings could be avoided.

Revolt of 1857
The Revolt of 1857 is also know as the first freedom national movement.
1. Political causes – Lord Wellesley’s subsidiary Alliance System succeeded in expanding the East India Company’s dominance through subjugation of Indian States so that they finally lost their independence. In addition many states were annexed by the Britishers under the Doctrine of Lapse introduced by Lord Dalhousie. He also refused to recognize titles of ex-rulers. The imperial Mughal glory suffered at the hands of company rule. In 1849 it was decided that the Mughal successors to Bhadurshah would have to shift from Red Fort to the outskirts of Delhi.
2. Economic Cause – The economic policies of the British in India completely destroyed India’s traditional economic fabric. The country was turned into a colonial economy serving the needs of the rulers mother country. The availability of cheaper machine made goods hit the handicraft sector, which could not compete in foreign markets because of higher import duties. India was forced to export raw materials on the thus domestic industries suffered as they had to purchase raw material at high prices.
3. Administrative Cause – The companies administrative machinery was not only inefficient but also prejudice against the Indian’s. Police and the judicial systems were racist. Indians were denied key positions in civil and military and they were rarely promoted.
4. Military Causes – The Indian sepoys were as displeased with alien rule as the people at large. The sepoys were denied all that they once enjoyed. The Post Office Act of 1854 withdrew even the free postage facility for them. The Indian sepoys considered inferior and treated badly. Could neither get paid properly nor easily avail of promotions.
5. Social and Religious Causes – Social discrimination of the British against the Indians and the missionaries attempted to spread Christianity in India. Convinced the Indian mind that the countries religion and culture would be violated. In social life the British treated the natives as inferiors. Despite being guilty of criminal assault on Indians the whites were acquitted with little punishment. Attempts by the English to end sati, child marriage and infanticide was suspiciously viewed and legislation of widow remarriage and introduction of western education antagonized the traditional Indian society.
Q. What was the immediate cause of the Revolt? Also describe briefly the revolt?
Ans. The Revolt of 1857 which is also considered as the first war of independence against British rule covered a significant area from Punjab in the North to Narmada in the South and from Bihar in the East to Rajputana in the West. However the focal points were Delhi, Kanpur, Lucknow, Baraily, Banaras, Jhansi, Meerut and Arrah.
The hanging of Mangal Pandey a soldier from Baragpur in March 1857 sparked a small revolt.
The immediate provocation was the use of greased cartridges. In May 1857 soldiers of the 3rd native cavalry at Meerut refused to use the Enfield riffle issued by the British. The riffles required to be refilled by biting off the top paper with the mouth. Rumor had it that the cartridge were smeared with cow and pig fat.
Spread of Revolt – The sepoys of Meerut in open rebellion marched to Delhi where the local infantry joined them. Many Britishers were captured some were killed also. At Delhi Bhadur Shah was declared the titular head of the ocuntry.
General Bakt khan from Baraley Regiment Captured Delhi. The revolt at Lucknow was led by Begum Hazrat Mahal of Awadh. At Kanpur Nana Sahib proclaimed himself the peshwan. He was supported by his rebel Lieutenant Tantya Tope and also by Assem Ulha. In Jhansi the revolting troops proclaimed Rani Lakshmi Bai the widow of Ganga Dhar Rao as the ruler. She also received the support from the troops of Sindias of Gwalior.
Q. Describe the causes for failure of revolt of 1857.
Ans. Through the revolt was a brave effort, it was doomed to fail owing to many weaknesses. The Revolt was a localised affair concentrated in portions of North India. Even from this area many rulers and chiefs did not participate. In fact, the educated upper and middle classes were critical of the mutiny.
The British formed a consulted programme to suppress the 1857 mutiny which through patriotic lacked a definite ideology. There was no central leader behind the revolt.
Compared to the superior weaponry and strategy of the British the war fare technique of the sepoys were out moded. The sepoys had a limited number of guns and fought mainly with swords, spears and these like.
Q. What was the impact of the revolt ?
And. The Indian Administration was placed directly under the crown by Government of India Act 1858. The East India Compny no longer required to manage the affairs inIndia, thus ending dualism. As per the act in Britain a Secretary of State for India was to be appointed who would be assisted by 15 member advisory council.
2. Recognising the role of the Indian states in the revolt it was decided ot preserve them as the bulwark of the empire. The Queen’s proclamation promised to discontinue the practice of annexation. The people were assured of religious freedom.
3. As the Indian army had begun the mutiny of 1857 the British made attempts to strengthen the military administration. European troops were increased in number. Most of the Indian artillery units were disbandoned and all effective weapons placed in European hands. All important posts were for the English alone.
4. Another significant decision was to involve Indians in legislation os that the rulers would be acquainted with the feeling and demands and misunderstandings could be avoided.

The Universe
The Universe
The universe is believed to be 50 billion years old. It consist of unimaginary huge space and stars. Stars are not uniformly scattered. They occur in clusters or galaxies.
In the second century B.C. a Greek astronomer Ptolmy declared that all bodies revolves around the earth.
Later on Copernicus gave the theory that the sun is the center of the Universe.
Big Bang theory
It is explained by a Belgium astronomer A.G. Lemeitre.
According to this theory billions of years ago cosmic matters i.e. the universe was in an extremely condensed state. A big explosion broke up the super dense ball and cast its fragments far out into space. It is from these speeding fragments of matter that our galaxy have been formed. The farthest pieces are flying the fastest.
Steady Sate Theory
It is exclaimed by Thoma Gold, Hermanbondi. It is know as the continuous creation theory. It states that as old galaxies move apart new galaxies are being formed from the new matter.
Pulsating Universe Theory
It is advocated by Dr. Alan. This theory states that the universe expand and contracts alternatively between period running into tens of billions of years.
Theory of geocentric universe was given by Ptolemy.
Almegest book was written by Ptolemy.
Stars
Stars are clusters of clouds and gasses. It contracts under its own gravitational force. The gradual shrinking process of the huge ball initially called Protostar, goes on till the fusion reaction begins.
The colour of the stars depend on the temperature of the stars.
Red stars are cooler than white stars.
White stars are cooler than blue stars.
Yellow stars are comparatively hot.
The stars which have consumed 10% of their fuel appears reddish because they grow in size are know as Red Giants.
The light from stars travel through different moving layers in the space with different densities and temperatures. This leads to the twinkling of the stars.
The brightest star in the sky is Sirius or Dog Star.
Distance between Earth and Alpha Century is 4.3 light years.
Parsec is the unit of measuring inter stellar distances. 1 Parsec = 3.26 light years.
All stars rises in the East and sets in the West.
Nebulae is the cloud of rarely found gasses which exists between stars and glows with the light of stars.
Initial stage of star is known as Protostar
Quaras are quasi stellar bodies emitting radio signals.
Black Hole or Neutron Stars
It is a type of star whose density is very high. Because of this high density its gravitational pull become so excessive that even the light rays can’t escape from it. Thus it can’t be seen by an optical telescope.
Supernovae – Are violent explosions of massive stars in which all but he inner core of the star is blown off. It leaves behind black holes or neutron stars.
Black holes are detected by Radio telescope.
Galaxies
Galaxies are giant clusters of stars. There are three types of galaxies.
i. Elliptical Shaped Galaxy - consist of older stars.
ii. Spiral Shaped Galaxy - consist of bright and young stars
iii. Irregular shape galaxy
Almost 75% of the galaxies are spiral shaped, 20% are elliptical and 5% are irregular shaped.
The galaxy of which our solar system is a part is known as Milky Way. It is a spiral shaped galaxy.
The nearest galaxy outside milky way is Megelton.
Another well known galaxy is Andromeda.
Milky way is a cluster of 150 billion stars. It is thicker in the middle and thins out at the edges. The sun which belongs to this galaxy is situated towards the North of central plain. All the stars in the milky way revolve around a centre. The galaxy is not uniformally bright.
Nearest galaxies to earth are Larch, Maglanic clouds & Small Maglenic Clouds.
Constellation
Is a closed group of stars which resemble the shape of an animal or human. Ursa Major, Great Bear, Orien etc. are constellations.
There are 88 constellations.
Orion, Great Bear, Pleides constellation of stars are seen during winter.
Scorpio is seen during summers.
Pole Star is the part of Ursa Major constellation.
Comets
Comets are luminous bodies with a tail moving round the sun in elliptical or parabolic path.
Elliptical comets are periodic while parabolic appears only once.
The tail is made up of gasses and dust. It develops when comet approach the sun and recedes when the comet moves away from the sun.
This tail always points away from the sun because of the repulsive force of the sun’s radiation.
Haley Comet appears after 76 years. It was first seen in 467 B.C. It was last seen in 1986.
Sun
Is a fixed type of star.
It is the centre of the solar system.
It is made up of extremely hot gasses mainly Hydrogen and Helium.
Energy is produced in the sun by the process of nuclear fission.
The stars closest of our solar system is known as Alfa Century or Proxima Century.
The sun is moving at a speed of 250 km/sec.
Sun takes about 250 years to complete one revolution round its centre. The period is called Cosmic Year.
Sun completes one rotation in 25 days 9 hrs and 4 mins.
It takes 8.3 mins. for the light to reach from sun to earth.
The glowing surface of sun is called Photosphere.
Above the photosphere is Chromospheres.
The outer most portion is called Corona, which is visible only during eclipse.
The visible light of the sun is made up of 7 colours VIBGYOR.
Sun light also contain Ultra Violet Rays and Infra Red Rays.
Ultra Violet rays have wave length shorter than the visible spectrum of VIBGYOR.
U.V. Rays are harmful for human beings and can cause skin cancer.
U.V. Rays are mostly absorbed by Ozone Layer present in the upper atmosphere.
The rays having larger frequency visible spectrum are known as Infra Red Rays. These rays are hot and are responsible for the heating effect.
The average distance between the earth and the sun is 149 million Kms.
The maximum distance being 152 Kms called Aphelion - 4th July
The minimum distance 147 Kms know as Perihelion -5th January.
Sun spots
At certain point on the sun’s surface the temperature is 4500 degree. These are the points from where extremely hot gasses escape in to the space. They work as the safety value of the sun.
Sun spots were discovered first of all by Galileo.
These spots have intense magnetic field.
The number of spots vary from year to year with a periodic cycle of 11 years.
This periodicity is known as sun spot cycle.
The expected life of the sun is 10 billion years.
Asteroids are small planets moving between orbits of Mass and Jupiter in a belt. Largest asteroid is Ceres.
Meteoroids are small bodies of mass which become luminous by friction on entering earth’s atmosphere they are popularly known as shooting stars.
Solar System
The solar system consist of Sun, Asteroids, 9 Planets & 32 Satellite.
Mercury - Closet to sun, smallest planet, No satellite, weak magnetic field, fastest moving, completes one revolution in 88 days.
Venus - closest to the earth, known as sister planet of the earth because of the similarity in physical fabric of the planet. It is the brightest, hottest planet known as morning star or evening star. It rotates in a clock wise direction. That is from east to west which is contrary to the motion of most other planets. Venus is named after the Roman Goddess of beauty.
Venus has an atmosphere in which carbon dioxide gas is found in plenty. This Co2 gas causes the green house effect & accumulates heats on Venus. Therefore Venus is the hottest planet.
Venus increases and decreases like Moon in size.
Mars – also known as planet with red spots. Known as world of valleys and volcanoes. It has two satellites Phobos (fear) and Deimos (terror). It has polar ice caps like earth. Its axis is tilted.
Jupiter – is the largest planet in the solar system. It is 11 times larger than the earth. It has 16 satellites. Ganymede, one of its satellite is the largest satellite in our solar system. Recently shoe-maker levy- 9 comet collided with it.
Saturn – is the 2nd largest planet known for its cosmos rings, magnetic fields, 23 satellites which is the maximum no of satellite any planet has. It is the slowest moving planet & completes one revolution in 30 years. Discovered by Galileo. Its biggest satellite is known as Titan.
Uranus - is not visible to naked eyes and was the first planet to be discovered telescopically by William Hershel in 1781. Like Venus it also rotates clock wise and has 15 satellites.
Neptune – It was discovered by J.G. Galle in 1846. It completes one rotation in 165 years because of inter-section of its orbit with that of Pluto it became the farthest planet for a temporary period of 20 years. Completes one revolution in 165 years has 8 satellites.
Pluto – is the smallest, coldest planet which will also become farthest in March 1999. It has 1 satellite. It is named after roman god of Underworld.
The four inner most planet in the Solar system namely Mercury, Venus, Earth & mars are known as terrestrial planets. Because they have a compact rocky surface like the earth.
Four other planets name Jupiter, Saturn, Uranus & Neptune are known as Jovian Planets as they have similarity with Jupiter.
Hallos
Are beautiful rings of colored light around sun & moon. They are caused by the reflection of light by ice crystals in the atmosphere.
Earth
Earth is the 3rd planet placed between Venus & Mars.
The shape of the earth is Oblate Spheroid, i.e., it bulges out at the equator and it flattened at the poles.
The reason for flattening the pole is that the rotation of earth develops outward a centrifugal force which is maximum at the equator.
The equatorial diameter – 12756 kms.
The Polar diameter - 12714 kms.
Circumference - 510,100,570 kms.
The speed of revolution is 107220 kms.
Geoid is the theoretical shape of the earth ignoring its surface irregularities.
Earth rotates from West to East in anti clock wise direction. It completes one rotation in 24 hrs w.r.t. sun. – This time period is known as SOLAR DAY.
Earth completes one rotation w.r.t. any fixed star in 23 hrs 56 mins 4 sec. This time period is known as SIDERIAL DAY.
Simultaneous with the rotation, the earth also moves round the sun known as Revolution.
Earth completes one revolution in 365 days 5 hrs 48 mins and 45 secs.
Earth revolves around the sun in a fixed path which is elliptical in shape and is known as ORBIT.
70% of the total surface area of the earth is covered with water called as Hydrosphere.
29% of the area is land portion and is known as Lithosphere.
The average thickness of Lithosphere is 60 Km.
The crust layers comprises of rocks, rich in Silicon and Aluminium – SIAL
Below SIAL lies MENTAL upto a depth of 2900 kms it consists of SIMA i.e. Silicon and Magnesium.
The core of the earth consist of metal in liquid form. It has a radius of 3400 Km. As Nickel and Iron are dominant in the core called NIFE.
NIFE accounts for the magnetism of the earth.
Six most abundant elements in the crust are
Oxygen 49.8%, Calcium & Sodium in smaller quantities.
Silicon 26.03%
Iron 4.12 %
ROTATION
Days and Nights are formed as a result of the rotation of the Earth. Another important effect of rotation is that winds and currents change their direction. They turn towards right in Northern Hemisphere and towards Left in Southern hemisphere. This law is given by Ferrel so it is known as Ferrel’s Law.
Change of seasons occur because of revolution of the Earth.
INCLINATION
The two hemisphere experiences summer when they are in the front of sun and winter when they are away from the sun.
The axis of the earth is an imaginary line passing through the centre of the earth.
The axis of the earth always points in the one direction in the space.
Earth spins round its axis which remain inclined at an angle of 661/2o to the plane of its orbit.
The ends of the axis are called poles one is North Pole and other South Pole.
Summers are hotter because summer days are longer than night. During day time earth absorbs heat from the sun and during night it radiates heat. Since days are longer the earth absorbs more heat and is able to radiate less heat. Heat accumulates and makes summer hotter.
Tropics are the turning points from where the sun starts reverse journey. 231/2o North of equator is known as Tropic of Cancer and 231/2o south is known as Tropic of Capricorn.
SOLSTICE
Is a date when sun shines over any tropic.
Sun shines vertically over Tropic of Capricorn on 22nd December – it lies in Southern hemisphere, as a result there is summer solstice in the southern hemisphere and winter solstice in Northern Hemisphere.
Sun shines vertically over Tropic of Cancer on 21st June – it lies in Northern hemisphere, as a result there is summer solstice in the northern hemisphere and winter solstice in Southern Hemisphere.
Equator represent imaginary line passing round the earth midway between north and south pole. It thus divide the earth in two equal halves i.e., Northern hemisphere and southern hemisphere.
Latitude is the angular distance from equator. They are the parallel liens to the equator. The latitude of equator and as we move towards poles the latitude rises. It is maximum i.e. 90o
Arctic Circle is the circle drawn at 231/2o North Pole.
Antarctic Circle is the circle drawn at 231/2o South Pole.
Meridians are imaginary lines drawn on the global map connecting the two poles. There are 360 meridians in all. For the sake of convenience the meridians passing through Greenwich is known as Prime Meridian. The distance between two successive meridian is 111 Kms and there is a time difference of 4 minutes.
Longitudes are equidistant lines drawn east to west of Greenwich meridian. They denote angular distances of a place east or west of the Prime meridian.
Torrid Zone – Tropic zone : The area between 231/2o North and South of equator ie. Between the poles the tropic of Cancer and tropic of Capricorn. This is the hottest zone since the rays of sun are nearly perpendicular than in any other zone.
Frigid zone : The area between the North pole and Arctic circle is known as North frigid zone and between South pole and Antarctic Circle is known as South Frigid Zone.
Temperate Zone : lies between 661/2o from poles. The region between tropic of Cancer and Arctic circle is known as North Temperate Zone.
The places within the Arctic circle and Antarctic circle remain in light for some period during their respective summer. There is a day of 24 hrs. This phenomenon can be seen at places on North and South pole. The places from where this phenomenon can be seen include Norway, North Russia, Greenland etc.
EQUINOX
Is the position when sun rays falls vertically over equator making the duration of days and nights equal through out the globe.
21st & 22nd March, which is know as Spring Equinox.
22nd and 23rd September called Autumn Equinox.
Eclipses
Lunar Eclipse
The earth rotates round the sun and the moon (a natural satellite of the earth) moves round it. Many times the earth comes between sun and moon. Since all bodies in the solar system take light and heat from the sun. Earth causes its shadow on the moon. This is known as Lunar Eclipse.
As the earth the moon and the sun are in the same plane the lunar eclipse occur only on a full moon day.
Solar eclipse
When moon comes between the sun and earth, it causes its shadow on the earth known as Solar eclipse. It happens only on a new moon day.
Tides
Is the periodic rise and fall of sea water. The rise and fall occur alternatively twice a day. The tides are caused by the gravitational pull of the moon and the sun on earth’s surface including the sea water. When moon and earth revolves around each other a centrifugal force is produced. Tides are caused twice a day.
Spring Tide
When sun and moon are in the same line they pull earth gravitationally in the same direction. The combined pull causes a high tide known as Spring Tide.
Neap Tides
When sun and moon are at right angle the gravitational pull is exerted in a opposite direction and tide’s caused are low. There are called Neap Tides.
Uses of tides
No delta is formed at the mouth of the river they remain navigable.
Sea water does not freeze .
Sea level do not rise
Tides carry away the mud brought by the rivers.
Winds having as speed between 56 & 72 kms is known as gale.
Winds having a speed of 72 to 112 kms are known as Storm
Rift valley is a long & Narrow valley formed by sinking of a portion of the earth.
A vast accumulation of ice which moves slowly till it melts and forms a river is known as Glaciers.
Ice Berg is a large mass of ice which is detached from Glacier & keeps floating in the sea.
Geyser is a fountain of hot water issuing from a hole which extend deep into the earth crust. It also contains minerals.
The local time of the place is 12.00 noon when sun shines vertically overhead. It varies from GMT @ of 4 mins for 1o change in longitude.
Greenwich Mean time (GMT/World Time) is U.K’s standard time. It is based on the local time of the Prime Meridian.
Standard time is the local time of a place used through out the country.
Indian Standard Time is local time of the place near Allahabad (Mirzapur) situated at 881/2o East longitude.

According to theory of continental drift the Indian Peninsula was part of Ancient continent part known as Gondwanaland , situated near South Pole from which it broke away and drifted Northward. The Indian sub-continent consist of 3 structural continent.
1. The Great Mountain wall of the North
2. The Northern Plains.
3. The Peninsular India.
India has several mountain ranges, chief among them are The Himalayas, The Vindiyala, The Satpuras, The Aravalies, The Western Ghats and The Eastern Ghats.
K2 or Godwin Austin of Karakoram Range is the highest Mountain peak of India, it has a height of 8611 meters.
The northern most range is known as the Great Himalayas or Himadari.

India is the 4th largest consumers of fertilizers.
Rivers of India can be divided into two groups.
Himalayan Rivers
The rivers of Peninsular India.
The Himalayan Rivers are generally snow fed and continue to flow throughout the year. The main river systems are
The Indus System – the Indus rises form the spring of Sengge Khabab which is located about 100 km North of Mansarovar. It flows North West for 200 km in Tibet before entering Kashmir. It is about 2900 km in length, large part of Indus basin in India lies in J&K, Himachal Pradesh & Punjab. Its main tributaries are Satluj, Beas, Ravi, Chenab and Jehlum.
The Ganga System – The Ganga is over 2500 km long. The Bhagirathi which is the main headwater of Ganga rises form Gangotri Glacies at Gomuk, an ice cave. At Devprayag the Alakhnanda joins Bhagirathi. Alakhnanda rises from Alka Puri Glacier. Mandakhni which is fed by Melted water of Ghorabari Glacier also joins them than this combine water taken the name Ganga. The tributaries of Ganga are Yamuna, Ghagar, Gomti, Kosi, Sone, Damodar and Gandhak.
At Raj Mahal hills Ganga is divided into two parts. Hugli which enters bay of Bengal. The other part which flows through Bangladesh is called Padma after meeting Bharamputra in South Bangladesh another river Meghna meets the main stream and than the joint stream is known as Meghna.
Yamuna is the most important tributary of Gangs it rises from Yamnotri Glacier which joins Ganga at Allahabad on right bank. Tributaries of Yamuna are Chambal, Betwa and Ken.
The Bharamputra rises in Tibet from Chema Yung dung Glacier near Mansarovar. It is slightly larger than Indus it flows in Tibet for 1250 km and is known as Tangspo. In Arunachal padesh it is known as Dihang. After confluence of Lohit, Dihang, and Manas it is known as Bharamputra. In the Northern Bangladesh before meeting Ganga it is known as Jamuna.
Nearly 70% of the people of India are dependant on agriculture. In India there are two cropping seasons
1. Kharif from July to October
2. Rabi from October to March.

Types of cultivation
1. Sedentary cultivation – also called settled cultivation, it is the practice of continued us e of land year after year i.e., normal practice.
2. Shifting cultivation – under this land is used for a few years until the fertility level drops when the farmer moves on to a new plot of land. Practiced mostly by tribal people, it is called Jhoom in Assam, Ponam in Kerala, Podu in Andhra Pradesh . Being highly wasteful a practice it is discouraged.
3. Terrace cultivation – In mountain areas cultivation is done on terraced fields in the same manner as settled cultivation in terms of land use. Terraces are made to check the rat eof soil erosion on steep slopes.
4. Wet farming – This is the practice of farming with the help of irrigation when the amount of rainfall fall short of requirement. Rice and Sugarcane are typical crops of this system of cultivation.
5. Dry cultivation – is done in areas where there are no irrigation facilities.
6. Crop rotation – This is the practice of growing different crops in succession so that the soil remains fertile. The rotation of crops may take 1 year or a number of years.
7. Multiple farming – Cultivation of crops and raising of cattle simultaneously is called mixed farming. This term is also used to denote the practice of growing two or more crops on the same plot of land.

The Universe
The universe is believed to be 50 billion years old. It consist of unimaginary huge space and stars. Stars are not uniformly scattered. They occur in clusters or galaxies.
In the second century B.C. a Greek astronomer Ptolmy declared that all bodies revolves around the earth.
Later on Copernicus gave the theory that the sun is the center of the Universe.
Big Bang theory
It is explained by a Belgium astronomer A.G. Lemeitre.
According to this theory billions of years ago cosmic matters i.e. the universe was in an extremely condensed state. A big explosion broke up the super dense ball and cast its fragments far out into space. It is from these speeding fragments of matter that our galaxy have been formed. The farthest pieces are flying the fastest.
Steady Sate Theory
It is exclaimed by Thoma Gold, Hermanbondi. It is know as the continuous creation theory. It states that as old galaxies move apart new galaxies are being formed from the new matter.
Pulsating Universe Theory
It is advocated by Dr. Alan. This theory states that the universe expand and contracts alternatively between period running into tens of billions of years.
Theory of geocentric universe was given by Ptolemy.
Almegest book was written by Ptolemy.
Stars
Stars are clusters of clouds and gasses. It contracts under its own gravitational force. The gradual shrinking process of the huge ball initially called Protostar, goes on till the fusion reaction begins.
The colour of the stars depend on the temperature of the stars.
Red stars are cooler than white stars.
White stars are cooler than blue stars.
Yellow stars are comparatively hot.
The stars which have consumed 10% of their fuel appears reddish because they grow in size are know as Red Giants.
The light from stars travel through different moving layers in the space with different densities and temperatures. This leads to the twinkling of the stars.
The brightest star in the sky is Sirius or Dog Star.
Distance between Earth and Alpha Century is 4.3 light years.
Parsec is the unit of measuring inter stellar distances. 1 Parsec = 3.26 light years.
All stars rises in the East and sets in the West.
Nebulae is the cloud of rarely found gasses which exists between stars and glows with the light of stars.
Initial stage of star is known as Protostar
Quaras are quasi stellar bodies emitting radio signals.
Black Hole or Neutron Stars
It is a type of star whose density is very high. Because of this high density its gravitational pull become so excessive that even the light rays can’t escape from it. Thus it can’t be seen by an optical telescope.
Supernovae – Are violent explosions of massive stars in which all but he inner core of the star is blown off. It leaves behind black holes or neutron stars.
Black holes are detected by Radio telescope.
Galaxies
Galaxies are giant clusters of stars. There are three types of galaxies.
i. Elliptical Shaped Galaxy - consist of older stars.
ii. Spiral Shaped Galaxy - consist of bright and young stars
iii. Irregular shape galaxy
Almost 75% of the galaxies are spiral shaped, 20% are elliptical and 5% are irregular shaped.
The galaxy of which our solar system is a part is known as Milky Way. It is a spiral shaped galaxy.
The nearest galaxy outside milky way is Megelton.
Another well known galaxy is Andromeda.
Milky way is a cluster of 150 billion stars. It is thicker in the middle and thins out at the edges. The sun which belongs to this galaxy is situated towards the North of central plain. All the stars in the milky way revolve around a centre. The galaxy is not uniformally bright.
Nearest galaxies to earth are Larch, Maglanic clouds & Small Maglenic Clouds.
Constellation
Is a closed group of stars which resemble the shape of an animal or human. Ursa Major, Great Bear, Orien etc. are constellations.
There are 88 constellations.
Orion, Great Bear, Pleides constellation of stars are seen during winter.
Scorpio is seen during summers.
Pole Star is the part of Ursa Major constellation.
Comets
Comets are luminous bodies with a tail moving round the sun in elliptical or parabolic path.
Elliptical comets are periodic while parabolic appears only once.
The tail is made up of gasses and dust. It develops when comet approach the sun and recedes when the comet moves away from the sun.
This tail always points away from the sun because of the repulsive force of the sun’s radiation.
Haley Comet appears after 76 years. It was first seen in 467 B.C. It was last seen in 1986.
Sun
Is a fixed type of star.
It is the centre of the solar system.
It is made up of extremely hot gasses mainly Hydrogen and Helium.
Energy is produced in the sun by the process of nuclear fission.
The stars closest of our solar system is known as Alfa Century or Proxima Century.
The sun is moving at a speed of 250 km/sec.
Sun takes about 250 years to complete one revolution round its centre. The period is called Cosmic Year.
Sun completes one rotation in 25 days 9 hrs and 4 mins.
It takes 8.3 mins. for the light to reach from sun to earth.
The glowing surface of sun is called Photosphere.
Above the photosphere is Chromospheres.
The outer most portion is called Corona, which is visible only during eclipse.
The visible light of the sun is made up of 7 colours VIBGYOR.
Sun light also contain Ultra Violet Rays and Infra Red Rays.
Ultra Violet rays have wave length shorter than the visible spectrum of VIBGYOR.
U.V. Rays are harmful for human beings and can cause skin cancer.
U.V. Rays are mostly absorbed by Ozone Layer present in the upper atmosphere.
The rays having larger frequency visible spectrum are known as Infra Red Rays. These rays are hot and are responsible for the heating effect.
The average distance between the earth and the sun is 149 million Kms.
The maximum distance being 152 Kms called Aphelion - 4th July
The minimum distance 147 Kms know as Perihelion -5th January.
Sun spots
At certain point on the sun’s surface the temperature is 4500 degree. These are the points from where extremely hot gasses escape in to the space. They work as the safety value of the sun.
Sun spots were discovered first of all by Galileo.
These spots have intense magnetic field.
The number of spots vary from year to year with a periodic cycle of 11 years.
This periodicity is known as sun spot cycle.
The expected life of the sun is 10 billion years.
Asteroids are small planets moving between orbits of Mass and Jupiter in a belt. Largest asteroid is Ceres.
Meteoroids are small bodies of mass which become luminous by friction on entering earth’s atmosphere they are popularly known as shooting stars.
Solar System
The solar system consist of Sun, Asteroids, 9 Planets & 32 Satellite.
Mercury - Closet to sun, smallest planet, No satellite, weak magnetic field, fastest moving, completes one revolution in 88 days.
Venus - closest to the earth, known as sister planet of the earth because of the similarity in physical fabric of the planet. It is the brightest, hottest planet known as morning star or evening star. It rotates in a clock wise direction. That is from east to west which is contrary to the motion of most other planets. Venus is named after the Roman Goddess of beauty.
Venus has an atmosphere in which carbon dioxide gas is found in plenty. This Co2 gas causes the green house effect & accumulates heats on Venus. Therefore Venus is the hottest planet.
Venus increases and decreases like Moon in size.
Mars – also known as planet with red spots. Known as world of valleys and volcanoes. It has two satellites Phobos (fear) and Deimos (terror). It has polar ice caps like earth. Its axis is tilted.
Jupiter – is the largest planet in the solar system. It is 11 times larger than the earth. It has 16 satellites. Ganymede, one of its satellite is the largest satellite in our solar system. Recently shoe-maker levy- 9 comet collided with it.
Saturn – is the 2nd largest planet known for its cosmos rings, magnetic fields, 23 satellites which is the maximum no of satellite any planet has. It is the slowest moving planet & completes one revolution in 30 years. Discovered by Galileo. Its biggest satellite is known as Titan.
Uranus - is not visible to naked eyes and was the first planet to be discovered telescopically by William Hershel in 1781. Like Venus it also rotates clock wise and has 15 satellites.
Neptune – It was discovered by J.G. Galle in 1846. It completes one rotation in 165 years because of inter-section of its orbit with that of Pluto it became the farthest planet for a temporary period of 20 years. Completes one revolution in 165 years has 8 satellites.
Pluto – is the smallest, coldest planet which will also become farthest in March 1999. It has 1 satellite. It is named after roman god of Underworld.
The four inner most planet in the Solar system namely Mercury, Venus, Earth & mars are known as terrestrial planets. Because they have a compact rocky surface like the earth.
Four other planets name Jupiter, Saturn, Uranus & Neptune are known as Jovian Planets as they have similarity with Jupiter.
Hallos
Are beautiful rings of colored light around sun & moon. They are caused by the reflection of light by ice crystals in the atmosphere.
Earth
Earth is the 3rd planet placed between Venus & Mars.
The shape of the earth is Oblate Spheroid, i.e., it bulges out at the equator and it flattened at the poles.
The reason for flattening the pole is that the rotation of earth develops outward a centrifugal force which is maximum at the equator.
The equatorial diameter – 12756 kms.
The Polar diameter - 12714 kms.
Circumference - 510,100,570 kms.
The speed of revolution is 107220 kms.
Geoid is the theoretical shape of the earth ignoring its surface irregularities.
Earth rotates from West to East in anti clock wise direction. It completes one rotation in 24 hrs w.r.t. sun. – This time period is known as SOLAR DAY.
Earth completes one rotation w.r.t. any fixed star in 23 hrs 56 mins 4 sec. This time period is known as SIDERIAL DAY.
Simultaneous with the rotation, the earth also moves round the sun known as Revolution.
Earth completes one revolution in 365 days 5 hrs 48 mins and 45 secs.
Earth revolves around the sun in a fixed path which is elliptical in shape and is known as ORBIT.
70% of the total surface area of the earth is covered with water called as Hydrosphere.
29% of the area is land portion and is known as Lithosphere.
The average thickness of Lithosphere is 60 Km.
The crust layers comprises of rocks, rich in Silicon and Aluminium – SIAL
Below SIAL lies MENTAL upto a depth of 2900 kms it consists of SIMA i.e. Silicon and Magnesium.
The core of the earth consist of metal in liquid form. It has a radius of 3400 Km. As Nickel and Iron are dominant in the core called NIFE.
NIFE accounts for the magnetism of the earth.
Six most abundant elements in the crust are
Oxygen 49.8%, Calcium & Sodium in smaller quantities.
Silicon 26.03%
Iron 4.12 %
ROTATION
Days and Nights are formed as a result of the rotation of the Earth. Another important effect of rotation is that winds and currents change their direction. They turn towards right in Northern Hemisphere and towards Left in Southern hemisphere. This law is given by Ferrel so it is known as Ferrel’s Law.
Change of seasons occur because of revolution of the Earth.
INCLINATION
The two hemisphere experiences summer when they are in the front of sun and winter when they are away from the sun.
The axis of the earth is an imaginary line passing through the centre of the earth.
The axis of the earth always points in the one direction in the space.
Earth spins round its axis which remain inclined at an angle of 661/2o to the plane of its orbit.
The ends of the axis are called poles one is North Pole and other South Pole.
Summers are hotter because summer days are longer than night. During day time earth absorbs heat from the sun and during night it radiates heat. Since days are longer the earth absorbs more heat and is able to radiate less heat. Heat accumulates and makes summer hotter.
Tropics are the turning points from where the sun starts reverse journey. 231/2o North of equator is known as Tropic of Cancer and 231/2o south is known as Tropic of Capricorn.
SOLSTICE
Is a date when sun shines over any tropic.
Sun shines vertically over Tropic of Capricorn on 22nd December – it lies in Southern hemisphere, as a result there is summer solstice in the southern hemisphere and winter solstice in Northern Hemisphere.
Sun shines vertically over Tropic of Cancer on 21st June – it lies in Northern hemisphere, as a result there is summer solstice in the northern hemisphere and winter solstice in Southern Hemisphere.
Equator represent imaginary line passing round the earth midway between north and south pole. It thus divide the earth in two equal halves i.e., Northern hemisphere and southern hemisphere.
Latitude is the angular distance from equator. They are the parallel liens to the equator. The latitude of equator and as we move towards poles the latitude rises. It is maximum i.e. 90o
Arctic Circle is the circle drawn at 231/2o North Pole.
Antarctic Circle is the circle drawn at 231/2o South Pole.
Meridians are imaginary lines drawn on the global map connecting the two poles. There are 360 meridians in all. For the sake of convenience the meridians passing through Greenwich is known as Prime Meridian. The distance between two successive meridian is 111 Kms and there is a time difference of 4 minutes.
Longitudes are equidistant lines drawn east to west of Greenwich meridian. They denote angular distances of a place east or west of the Prime meridian.
Torrid Zone – Tropic zone : The area between 231/2o North and South of equator ie. Between the poles the tropic of Cancer and tropic of Capricorn. This is the hottest zone since the rays of sun are nearly perpendicular than in any other zone.
Frigid zone : The area between the North pole and Arctic circle is known as North frigid zone and between South pole and Antarctic Circle is known as South Frigid Zone.
Temperate Zone : lies between 661/2o from poles. The region between tropic of Cancer and Arctic circle is known as North Temperate Zone.
The places within the Arctic circle and Antarctic circle remain in light for some period during their respective summer. There is a day of 24 hrs. This phenomenon can be seen at places on North and South pole. The places from where this phenomenon can be seen include Norway, North Russia, Greenland etc.
EQUINOX
Is the position when sun rays falls vertically over equator making the duration of days and nights equal through out the globe.
21st & 22nd March, which is know as Spring Equinox.
22nd and 23rd September called Autumn Equinox.
Eclipses
Lunar Eclipse
The earth rotates round the sun and the moon (a natural satellite of the earth) moves round it. Many times the earth comes between sun and moon. Since all bodies in the solar system take light and heat from the sun. Earth causes its shadow on the moon. This is known as Lunar Eclipse.
As the earth the moon and the sun are in the same plane the lunar eclipse occur only on a full moon day.
Solar eclipse
When moon comes between the sun and earth, it causes its shadow on the earth known as Solar eclipse. It happens only on a new moon day.
Tides
Is the periodic rise and fall of sea water. The rise and fall occur alternatively twice a day. The tides are caused by the gravitational pull of the moon and the sun on earth’s surface including the sea water. When moon and earth revolves around each other a centrifugal force is produced. Tides are caused twice a day.
Spring Tide
When sun and moon are in the same line they pull earth gravitationally in the same direction. The combined pull causes a high tide known as Spring Tide.
Neap Tides
When sun and moon are at right angle the gravitational pull is exerted in a opposite direction and tide’s caused are low. There are called Neap Tides.
Uses of tides
No delta is formed at the mouth of the river they remain navigable.
Sea water does not freeze .
Sea level do not rise
Tides carry away the mud brought by the rivers.
Winds having as speed between 56 & 72 kms is known as gale.
Winds having a speed of 72 to 112 kms are known as Storm
Rift valley is a long & Narrow valley formed by sinking of a portion of the earth.
A vast accumulation of ice which moves slowly till it melts and forms a river is known as Glaciers.
Ice Berg is a large mass of ice which is detached from Glacier & keeps floating in the sea.
Geyser is a fountain of hot water issuing from a hole which extend deep into the earth crust. It also contains minerals.
The local time of the place is 12.00 noon when sun shines vertically overhead. It varies from GMT @ of 4 mins for 1o change in longitude.
Greenwich Mean time (GMT/World Time) is U.K’s standard time. It is based on the local time of the Prime Meridian.
Standard time is the local time of a place used through out the country.
Indian Standard Time is local time of the place near Allahabad (Mirzapur) situated at 881/2o East longitude.

According to theory of continental drift the Indian Peninsula was part of Ancient continent part known as Gondwanaland , situated near South Pole from which it broke away and drifted Northward. The Indian sub-continent consist of 3 structural continent.
1. The Great Mountain wall of the North
2. The Northern Plains.
3. The Peninsular India.
India has several mountain ranges, chief among them are The Himalayas, The Vindiyala, The Satpuras, The Aravalies, The Western Ghats and The Eastern Ghats.
K2 or Godwin Austin of Karakoram Range is the highest Mountain peak of India, it has a height of 8611 meters.
The northern most range is known as the Great Himalayas or Himadari.
The Peer Panjal lies in Kashmir and Khaula Khar in Jammu belong to middle Himalayas.

Gurushikhar on the habbu hills is the highest peak of Aravalies (Rajasthan).
India is the 4th largest consumers of fertilizers.
Rivers of India can be divided into two groups.
Himalayan Rivers
The rivers of Peninsular India.
The Himalayan Rivers are generally snow fed and continue to flow throughout the year. The main river systems are
The Indus System – the Indus rises form the spring of Sengge Khabab which is located about 100 km North of Mansarovar. It flows North West for 200 km in Tibet before entering Kashmir. It is about 2900 km in length, large part of Indus basin in India lies in J&K, Himachal Pradesh & Punjab. Its main tributaries are Satluj, Beas, Ravi, Chenab and Jehlum.
The Ganga System – The Ganga is over 2500 km long. The Bhagirathi which is the main headwater of Ganga rises form Gangotri Glacies at Gomuk, an ice cave. At Devprayag the Alakhnanda joins Bhagirathi. Alakhnanda rises from Alka Puri Glacier. Mandakhni which is fed by Melted water of Ghorabari Glacier also joins them than this combine water taken the name Ganga. The tributaries of Ganga are Yamuna, Ghagar, Gomti, Kosi, Sone, Damodar and Gandhak.
At Raj Mahal hills Ganga is divided into two parts. Hugli which enters bay of Bengal. The other part which flows through Bangladesh is called Padma after meeting Bharamputra in South Bangladesh another river Meghna meets the main stream and than the joint stream is known as Meghna.
Yamuna is the most important tributary of Gangs it rises from Yamnotri Glacier which joins Ganga at Allahabad on right bank. Tributaries of Yamuna are Chambal, Betwa and Ken.
The Bharamputra rises in Tibet from Chema Yung dung Glacier near Mansarovar. It is slightly larger than Indus it flows in Tibet for 1250 km and is known as Tangspo. In Arunachal padesh it is known as Dihang. After confluence of Lohit, Dihang, and Manas it is known as Bharamputra. In the Northern Bangladesh before meeting Ganga it is known as Jamuna.
Nearly 70% of the people of India are dependant on agriculture. In India there are two cropping seasons
1. Kharif from July to October
2. Rabi from October to March.
Wheat : Its plant require cool climate in the beginning and hot weather at the time of harvesting. It needs an annual rainfall of 20 inches to 30 inches. Clay soil is the most favorable soil. Largest producer is UP.
Sugarcane : India is the largest sugarcane producing county in the world. It accounts for nearly 37% of the total world’s production. UP is the largest producer.
Tea : India is largest tea producing country but it is being closely followed by China & Srilanka. Tea is grown on mountain slopes and requires at least 60 inches rain fall, stagnant water spoils the tea plant so step cultivation is resorted to. Largest producer is Assam.

Types of cultivation
1. Sedentary cultivation – also called settled cultivation, it is the practice of continued us e of land year after year i.e., normal practice.
2. Shifting cultivation – under this land is used for a few years until the fertility level drops when the farmer moves on to a new plot of land. Practiced mostly by tribal people, it is called Jhoom in Assam, Ponam in Kerala, Podu in Andhra Pradesh . Being highly wasteful a practice it is discouraged.
3. Terrace cultivation – In mountain areas cultivation is done on terraced fields in the same manner as settled cultivation in terms of land use. Terraces are made to check the rat eof soil erosion on steep slopes.
4. Wet farming – This is the practice of farming with the help of irrigation when the amount of rainfall fall short of requirement. Rice and Sugarcane are typical crops of this system of cultivation.
5. Dry cultivation – is done in areas where there are no irrigation facilities.
6. Crop rotation – This is the practice of growing different crops in succession so that the soil remains fertile. The rotation of crops may take 1 year or a number of years.
7. Multiple farming – Cultivation of crops and raising of cattle simultaneously is called mixed farming. This term is also used to denote the practice of growing two or more crops on the same plot of land.
