Axis is an imaginary line passing through the centre of the earth and coming out from the earth at the North Pole and the South Pole. The spinning of the earth on its own axis is called rotation. Earth spins on its axis once every 24 hours.

The fixed path on which the earth moves around the sun is called an orbit. The earth moves around the sun in a fixed path known as the orbit. The movement of the earth in this circular orbit around the sun is called revolution. It takes 365 days to complete one revolution around the sun. Revolution causes the seasons to change.

The spinning movement of the earth on its axis is called rotation. Due to rotation, only half of the earth faces the sun thus experiencing daylight while the other half experiences night. The earth completes one rotation in 24 hours.

The movement of the earth around the sun in a fixed path is called revolution. The earth revolves around the sun and it takes one year to complete one revolution. The revolution and axis tilt together cause the change in seasons. When the earth is closest to the sun, it is summer and when the earth is the farthest away from the sun, we experience winter.
