Tides

The Tides are the rise and fall of sea levels experienced on coastlines at different parts of the earth. Tides occur on the oceans and inland seas, while lakes and rivers often do not experience tidal effects. Despite the popular explanation of the cause of tides as being due to the gravitational attraction of the moon and sun, the workings of the tides remains a generally unsolved issue in science. Issac Newton is said to have considered the tides to be the least satisfactory part of his theory of gravitation¹.
