If it is the Moon that determines ( in part) the effect of "Tides" - why are there two tides each day ( in most places) when there is only one Moon rotation of the Earth??

Essentially, the water on the near side is pulled up and away from the Earth, while on the far side the land masses are pulled toward the Moon and away from the water.

As the Earth rotates with respect to the Moon, the water level alternately rises and falls as these bulges of water are swept around the world. Since there are two bulges, there are two high tides per day. Because of the tilt of the Earth's axis, a location can have two unequal high or two unequal low tides in a day.
