The revolution of Earth gives us day and night. This is when the Earth rotates on its axis, changing the time of day, as well as the seasons.
The main events are: 1. Winter solstice - when the earth is tilted towards the sun. 2. Spring equinox - when day and night are equal in length. 3. Summer solstice - when the earth is tilted away from the sun. 4. Autumnal equinox - when day and night are equal in length.
The movement of Earth on its own axis is called Rotation and it causes day and night.
