Earth orbits the sun. Earth spins on its axis. The sun only transmits light energy during the daytime. The sun only transmits light energy above the equator.
I gave my students this multiple choice question: Which explains the pattern of day and night?

Only one answer is correct among these 4 choices:
- Earth orbits the sun.
- Earth spins on its axis.
- The sun only transmits light energy during the daytime.
- The sun only transmits light energy above the equator.

Could you tell me which one is correct?
