Detailed explanation-1: -On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge. On the far side of the Earth, inertia dominates, creating a second bulge. In this way the combination of gravity and inertia create two bulges of water.
Detailed explanation-2: -It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Cool, dry air is denser than warm, humid air, and cool, salty water is denser than warm, less salty water. Gravity pulls denser air and water downward, forcing less dense air and water to move upward.
Detailed explanation-3: -The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur.
Detailed explanation-4: -Molecules of water near Earth’s poles are pulled mostly straight down toward the planet’s center of gravity (near its core), and the molecules closest to the Moon (at Earth’s equator) experience the strongest pull toward the Moon.
