Rotation and Revolution of Earth

The video explains how Earth moves through rotation and revolution. Earth's rotation on its axis causes day and night, while its revolution around the sun defines the year. A full rotation takes 24 hours, and a full revolution takes about 365.24 days, leading to leap years every four years. These movements are crucial for understanding time, seasons, and the length of days.
