Earth's Rotation and Revolution Concepts

The video explains how Earth moves through rotation and revolution. Earth's rotation on its axis creates day and night, while its revolution around the sun defines the year and seasons. A full rotation takes 24 hours, and a revolution takes about 365.24 days, leading to leap years. These movements are crucial for measuring time and understanding the natural phenomena of lightness, darkness, and seasonal changes.

How does Earth move in space?

Why do we have leap years?

• To celebrate a special event

• To adjust for Earth's rotation

• To account for the extra 0.24 days in Earth's revolution

• To align with the lunar calendar

What is added to the calendar during a leap year?

• An extra week

• An extra month
