What causes tides in the oceans around the world?
Actually, the moon affects the ocean tides around the world. The gravitational pull of the moon tugs on the surface of the ocean until its surface mounds up and outward in the direction of the moon. When the mound of water has reached its highest point it is called high tide. On the side of the earth opposite the moon, the centrifugal force caused by the earth’s rotation produces another mound of water and high tide on the opposite side of the earth. Somewhere in between these two high tides are two flat areas on the surface of the ocean, these are low tides.
