INDIAN GEOGRAPHY 2014 notes

Geography

Earth-The earth is an oblate spheroid and not a true sphere,because it is flattened at the poles and bulges out at the equator.Its circumference is 25,000 miles.

Earth in Motion-The axis of the earth is the imaginary line on which the earth rotates.

Poles-They are the end of the axis.One end is called North Pole and other the South Pole.

The Solar System-It is the name given to the group of nine major planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) and their satellites,asteroids

and hundreds of meteorites which evolve around the sun.They are kept in position on account of the pull of the sun on the planets.
