Understanding Day and Night

The video explains why it is day in some parts of the world and night in others simultaneously. It introduces the concept of Earth's rotation on its axis, which takes 24 hours to complete, resulting in day and night. The video clarifies that the sun does not move; instead, Earth rotates, causing different parts to face the sun or move away from it. This movement explains why we see the sun rise and set. The video also touches on daily activities associated with day and night and encourages viewers to learn more through their channel.
