Detailed explanation-1: -Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
Detailed explanation-2: -High tides and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth-and its water-to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Detailed explanation-3: -When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides-both commonly called spring tides.
Detailed explanation-4: -Centrifugal force of the Earth.
