What are the effects of rotation and revolution?

The rotation and revolution of the Earth cause various natural phenomena like day and night, seasons, and temperature variations.

1. Effects of Rotation

Rotation is the spinning of the Earth on its axis from west to east once every 24 hours.

• Causes day and night.
• Leads to apparent movement of the Sun across the sky.
• Causes time differences between longitudes.
• Leads to flattening of poles and bulging at the equator.
• Responsible for the Coriolis effect which affects wind and ocean currents.

2. Effects of Revolution

Revolution is the movement of the Earth around the Sun in an elliptical orbit once every 365¼ days.

• Causes different seasons due to the tilt of Earth's axis.
• Changes the apparent position of the Sun throughout the year.
• Determines the length of a year.
