Earth's Rotation and Seasons Concepts

The video tutorial explains the concepts of Earth's rotation and revolution. It describes how rotation causes day and night, while revolution around the sun leads to the changing seasons. The tutorial also covers the concept of leap years, explaining why an extra day is added to the calendar every four years. The importance of these astronomical phenomena in understanding time and seasons is emphasized.

What is the primary cause of day and night on Earth?

• Earth's rotation on its axis
