Our Tides

Beachcomber Discovery

The combined gravitational forces of primarily the moon and secondly the sun creates a powerful pull on planet earth, this pull is even more apparent on the earths large bodies of water
Due to the cyclic rotation of the earth and moon, the tidal cycle is 24 hours and 52 minutes long. During this time, any point on the earth's surface experiences two high tides and two low tides.
The tidal bulge that occurs during high tide in the worlds oceans follows the revolution of the moon. The water of the entire world is pulled by the moon's gravity. On the opposite side of the earth, simultaneously there is a high tide due to the inertia of the ocean water when the earth is being pulled toward the moon by its gravitational field yet the ocean water remains left behind because of the centrifugal force caused by the earths rotation, this means there is a high tide on both sides of the earth at the same time, points on the sides of the earth between the two tidal bulges experience low tide.
When the sun, moon, and the earth are lined up, the sun and moon are exerting their strongest force together and tidal ranges are at their maximum. This is known as spring tide. This occurs twice each month, when the moon is full or new.

A hint at our own aquatic past is suggested in a correlation between the human menstrual cycle and the lunar cycle. Many aquatic species follow the same lunar cycles influence on the tides for reproduction.
