Movements of Earth
The earth moves continuously. It has two different types of movements: rotation and revolution. Rotation gives rise to day and night :
- Movements: Spins on its axis like a top. The spinning motion of the Earth on its axis is called rotation.
- Earth rotates on a tilted axis. It takes about 24 hours to rotate once on its axis. The rotation of the Earth on its axis causes the formation of day and night. As the Earth rotates, the half that faces the Sun receives sunlight and has a day while the other half remains in darkness as it does not receive any sunlight. This half has night.
