Which of the 3 motions of the ocean is controlled by the moon's gravitational pull? Currents
Ridges
Waves
Tides

The tides are controlled by the Moon's gravitational pull.

Explanation:

An ocean motion that is controlled by the Moon's gravitational pull is the tides. The tides occur because the Moon manages to pull the water on Earth's surface toward it, so the water level gets higher on the side of Earth that's facing the Moon and on the opposite side. The water on the sides of Earth doesn't get pulled, but because the water is pulled toward the other sides, the water there retracts and the water level drops.

The tides vary in their levels, depending on the intensity of the gravitational pull from the Moon. This results in extremely high tides and extremely low tides in some parts of the month, or in very small high and low tides in other parts of the month. The tides have good and bad aspects about them, and humans have tried their best to use the good sides of them in full.
