night and day cloud formation phases of the Moon changing of the seasons
I gave my students this multiple choice question: Martin is writing a report for science class about how the tilt of Earth affects living organisms. Which subject should Martin include in his report that is directly affected by Earth's tilt?

Only one answer is correct among these 4 choices:
- night and day
- cloud formation
- phases of the Moon
- changing of the seasons

Could you tell me which one is correct?

changing of the seasons
