El día y la noche

The video explains how Earth's rotation causes day and night. As the Earth rotates on its axis every 24 hours, different parts of the planet experience daylight and darkness. The equator rotates faster than the poles, creating an illusion of the sun and moon moving across the sky. During the day, the sun is visible unless obscured by clouds, and the moon can sometimes be seen. At sunset, the sun appears to set due to Earth's rotation, leading to nighttime when stars and the moon become visible. The moon reflects sunlight, unlike stars that emit their own light.
