How do rotation and revolution explain sunrise and sunset?

Sunrise and sunset are explained by the rotation and revolution of the Earth. The Earth rotates on its axis, causing the appearance of the sun rising in the east and setting in the west. As the Earth revolves around the sun, the angle at which sunlight hits different parts of the Earth changes, leading to the changing lengths of days and nights throughout the year. This phenomenon is known as the Earth's axial tilt, which causes the changing seasons and the variation in the timing of sunrise and sunset.
