Earth is much closer to the Moon than to the Sun. The Sun's gravity is a factor only during the day. The Moon's core has a much greater density than the Sun's core. The Sun's mass is smaller than the mass of the Moon.
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: Tides, such as those along the coast of Massachusetts, are caused by gravitational attractions acting on Earth. Why is the gravitational attraction of the Moon a greater factor in determining tides than the gravitational attraction of the much larger Sun?
Possibilities:
- Earth is much closer to the Moon than to the Sun.
- The Sun's gravity is a factor only during the day.
- The Moon's core has a much greater density than the Sun's core.
- The Sun's mass is smaller than the mass of the Moon.

Earth is much closer to the Moon than to the Sun.
