the phases of the Moon the effects of gravitation the effects of volcanic eruptions the consequences of earthquakes
I gave my students this multiple choice question: What would a model of the Sun, Earth, and Moon best help students visualize?

Only one answer is correct among these 4 choices:
- the phases of the Moon
- the effects of gravitation
- the effects of volcanic eruptions
- the consequences of earthquakes

Could you tell me which one is correct?

the phases of the Moon
