High tide and low tide

The occurrence of high tides depends on the position of the moon. Since moon revolves around the Earth, the part of the Earth that faces the moon changes. The moon’s gravitational pull is strongest on the part of the Earth that faces the moon and when that part is a part of ocean then the water there bulges towards the moon.

Moon's gravitational force pulls on water in the oceans so that there are "bulges" in the ocean on both sides of the Earth. The moon pulls water toward it, and this causes the bulge toward the moon.

The bulge on the side of the Earth opposite the moon is caused by the moon "pulling the Earth away" from the water on that side.

If we are on the coast and the moon is directly overhead, we experience a high tide. If the moon is directly overhead on the opposite side of the planet, we experience a high tide.
