Moon and Ocean

[aazaya]

I have heard that people or some TV shows saying that ocean wave is influenced or formed by the gravity of the moon.what is it really?

[Klaynos]

Tides are due mostly to the influence of the moons gravity. There is even a tide on dry land, but because rock is harder to move than water it is significantly smaller.

 

The moon itself is locked and has a perminante tide due to the earth.
