the rotation of Earth on its axis the tilt of Earth's axis relative to the sun the location of Earth's orbit in the solar system the motion of the moon as it travels around Earth
I gave my students this multiple choice question: Which explains the relationship between hours of sunlight and seasons?

Only one answer is correct among these 4 choices:
- the rotation of Earth on its axis
- the tilt of Earth's axis relative to the sun
- the location of Earth's orbit in the solar system
- the motion of the moon as it travels around Earth

Could you tell me which one is correct?

the tilt of Earth's axis relative to the sun
