The Earth’s rotation about its axis affects its relation to ocean tides by the cause of one side of the Earth that faces the moon, the ocean’s surface bulge because of the moon's gravitational pull on water. On the opposite side of the Earth, water bulges because of rotation of the Earth. As well as the revolution of the moon around the Earth. Tides are due to the Earth’s spin. Tides are the rise and fall of sea levels. When the position changes so does the surface elevation. Tides are affected by the Earth’s rotation over time, as a result that some tides happen half-daily, or some may come
