The revolution of earth around the sun and the tilt of earth’s axis cause the changing of seasons. TRUE
<u>Explanation:</u>
Earth is slightly tilted at its axis. This causes a change in the amount of sunlight reaching each hemisphere.

The hemisphere closer to the sun will experience summer and the hemisphere away from the sun will experience winter.
