A lunar day is shorter. A lunar eclipse lasts longer. Earth moves closer to the Sun. Earth's tides decrease in size.
I gave my students this multiple choice question: What is the most likely outcome of the Moon moving away from Earth?

Only one answer is correct among these 4 choices:
- A lunar day is shorter.
- A lunar eclipse lasts longer.
- Earth moves closer to the Sun.
- Earth's tides decrease in size.

Could you tell me which one is correct?

Earth's tides decrease in size.
