History, Theories Of Tidal Action, Variables Affecting Tidal Forces, Tide Tables, Semidiurnal And Diurnal Tides

Tides are deformations in the shape of a body caused by the gravitational force of one or more other bodies. All bodies in the universe exert tidal forces on each other, although the effects are generally too small to observe. As far Earth is concerned, the most important tidal phenomena are the ocean and ground tides that occur as a result of the Moon's and the Sun's gravity.
