Description:

This document explains the predictable and periodic movements of ocean waters that are known as tides and how they are produced by the gravitational forces of the moon and sun. It describes how gravitational attraction and centrifugal force create bulges on either side of the Earth (the high tides), and how two coinciding and simultaneous low tides occur at equal distances around the earth between them. It also explains tidal range and why it varies greatly with geographic location.
