Movements of the Earth.
Rotation and revolution are the two movements of the Earth.
1. Rotation gives place to day and night. It´s the movement of the Earth on its axis. Each rotation of the Earth takes 24 hours to complete.
2. Revolution produces the *seasons. It´s the movement of the Earth around the Sun. Each revolution of the Earth takes 365.25 days to complete.
* The tilt of the Earth´s axis when it revolves around the Sun produces the four seasons. These depend on the angle of the Sun´s rays when they reach the Earth´s surface.
