What causes day and night?

Explanation:
Day and night come from Earth spinning on its axis. As the planet rotates, different parts of its surface move into and out of the Sun’s light. When your location faces the Sun, you have daylight; as the surface turns away, you experience night. This daily rotation makes the Sun appear to rise in the east and set in the west, completing a cycle in about 24 hours. The tilt of Earth's axis causes seasonal changes in how long daylight lasts at different times of year, but the existence of day and night itself is due to rotation.
