of

Moon?​

Answer 1

Answer:

While both the Moon and the Sun influence the ocean tides, the Moon plays the biggest role. Although the Sun's gravitational pull on the Earth is 178 times stronger than the Moon's, the tidal bulges it causes are much smaller.

This is because, contrary to common belief, tides are not caused by the gravitational forces of the Moon or the Sun lifting up the oceans—their gravitational pull is much too weak for that. Rather, tides are created because the strength and direction of the gravitational pull varies depending on where on Earth you are. This variation creates the differential forces or tidal forces that in turn cause tides.

The tidal forces of the Moon are much stronger than the Sun's because it is so much closer to our planet, causing a much greater variation in the gravitational force from one location to another. The Sun's gravitational force, on the other hand, varies much less because the Sun is so far away.
