Question 11

Why is the moon more important for tides than the sun?

Accepted Answer

The moon is closer to Earth, so its gravity pulls more strongly on the oceans. Even though the sun is bigger, its effect is smaller because it’s so far away.

Question 12

Do tides happen at the same time every day?
