Earth's Movements: Unraveling Rotation and Revolution

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 and seasons. The rotation takes 24 hours, creating day and night cycles, and the revolution takes about 365.24 days, leading to leap years every four years. These movements are crucial for measuring time and understanding seasonal changes.
