How does the rotation of the Earth cause day and night?

Answer 1

Simpler than you think...

When the part of Earth you're on is facing away from the Sun, you would experience nighttime (darker the further away from the Sun you are). When the part of the Earth you're on is facing towards the Sun, you would experience daytime.

The rotation of the Earth causes day and night as one side of the Earth faces the Sun, experiencing daylight, while the other side faces away from the Sun, experiencing darkness. This rotation takes approximately 24 hours to complete, resulting in the cycle of day and night.
