Tides are deformations in the shape of a body caused by the gravitational force of one or more other bodies. At least in theory, any two bodies in the Universe exert such a force on each other, although obvious tidal effects are generally too small to...

Visitors to the Outer Hebrides Islands off the west coast of Scotland might be surprised to find palmetto trees, transplanted from warmer climes, surviving at 58 ° latitude. Across the Atlantic, along the coast of Labrador, icebergs drift southward...

any of the cyclic deformations of one astronomical body caused by the gravitational forces exerted by others. The most familiar are the periodic variations in sea level on the Earth that correspond to changes in the relative positions of the Moon and...

Regular, periodic rise and fall of the surface of the sea, occurring in most places twice a day. Tides result from differences in the gravitational forces exerted at different points on the Earth's surface by another body (such as the Moon). Although...

A rising tide lifts all boats. (Roman) Boats sail with the tide. (Korean) Every tide has its ebb. (Irish) The greater the tide, the greater the ebb. (Welsh) The tide will fetch away what the ebb brings. (Spanish) Time and tide wait for no one. (Irish)...

Periodic rise and fall of the ocean surface. The forcing is derived from the gravitational attraction of the moon, sun and other planets. The moon plays the dominant role due to its close...
