Before explaining how the Moon does this, first let s define what tides are. Ocean tides are the regular rise and fall of waters as Earth experiences gravitational pull by other members of our solar system.
Gravitational pull is merely the attraction of matter to other matter.
Ocean tides are the consistent rise and fall of the waters as Earth feels the gravitational pull. High tide is when the ocean swells to its highest point which occurs approximately every thirteen hours. Low tide, therefore, is when waters sink to their lowest level. The Sun, the Moon and the planets all pull on the waters and land of the Earth. The Moon also exerts a noticeable pull on the Earth.
