tide wiki:
[ide is the regular rising and falling of the ocean's surface caused by changes in gravitational forces external to the Earth. The main changing gravitational field is due to the Moon while a lesser field is caused by the Sun.Since tides generate currents of conducting fluids within the Earth's magnetic field, they affect in return the magnetic field itself.The loss of rotational energy of the earth, due to friction within the tides, and the gravitational effects caused by tidal deformations of the earth's body, are responsible for the slowdown of the earth's rotation and the increase of the distance to the moon, see Tidal force.
