Tides are one of the most reliable phenomena in the world. As the sun rises in the east and the stars come out at night, we are confident that the ocean waters will regularly rise and fall along our shores. [1] At their peak, tides are known to be at high tide, at their nadir, tides are known to be at low tide.
Tides on the Earth result from the Moon's gravity, which is just enough stronger on the near side of the earth to attract ocean water more than on the far side. Fishermen, sailors and other observers have long noted that the twice-daily cycle of high tides and low tides is corresponds to the moon's orbit.
