Earth's Rotation and Day-Night Cycle

The video explains the phenomenon of day and night, which is caused by the Earth's rotation on its axis. The axis is an imaginary line tilted at 23.5 degrees. As the Earth rotates, the side facing the Sun experiences daylight, while the opposite side is in darkness, experiencing nighttime. This rotation takes 24 hours to complete, creating the daily cycle of day and night.
