Explanation:

Day and night are caused by the Earth rotating on its axis. As the Earth spins, different parts of it face the Sun (day) or are in shadow (night). The revolution of the Earth around the Sun causes the seasons, the tilt of the Earth's axis is related to the changing seasons and length of days at different times of the year, and 24 hours is the time - period of one complete rotation but not the cause itself.

the rotation of the Earth on its axis
