"Days and Nights"

"Days and nights" refer to the regular cycle of light and dark experienced on Earth, caused by its rotation. As Earth spins on its axis approximately every 24 hours, one half faces the Sun, experiencing daylight (day), while the other half faces away, experiencing darkness (night). This cycle creates the pattern of day and night, which influences daily human activities, weather, and ecosystems. The duration of day and night varies with latitude and season, but the fundamental mechanism remains Earth's consistent rotation relative to the Sun.
