the rotation of Earth on its axis the revolution of the Sun around Earth the Earth’s distance from the Sun the properties of Earth’s atmosphere
I gave my students this multiple choice question: The Sun appears to move across the sky each day, rising in the east and setting in the west. What causes this apparent motion?

Only one answer is correct among these 4 choices:
- the rotation of Earth on its axis
- the revolution of the Sun around Earth
- the Earth’s distance from the Sun
- the properties of Earth’s atmosphere

Could you tell me which one is correct?
