The cycle of day and night is caused by Earth's rotation on its axis. Imagine a spinning top; that's similar to how Earth rotates. This rotation takes approximately 24 hours to complete, which we experience as one day. As Earth rotates, different parts of the planet face the Sun, resulting in daylight. The side facing away from the Sun experiences night. It's a continuous cycle, bringing sunrise and sunset to different locations around the globe.
