• Effect: It causes day and night.

• Time Taken: The Earth completes one full rotation in 24 hours (1 day).

• Example: When the Earth rotates, the side facing the Sun experiences day, while the opposite side has night.

Revolution:

• Definition: Revolution is the movement of the Earth around the Sun in an elliptical orbit.

• Effect: It causes seasons (summer, winter, spring, autumn).

• Time Taken: The Earth completes one full revolution in 365¼ days (1 year).

• Example: Different parts of the Earth receive varying amounts of sunlight throughout the year, leading to seasonal changes.
