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: -Twice a month, when the Earth, Sun, and Moon line up, their gravitational power combines to make exceptionally high tides, called spring tides, as well as very low tides where the water has been displaced. When the Sun is at a right angle to the Moon, moderate tides, called neap tides, result.

Detailed explanation-3: -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-4: -THE TIDAL PHENOMENON The periodic rising and falling of the water surface of the ocean, seas, bays, mouths of rivers, etc., as a result of the gravitational attraction of the moon and sun on the earth is known as the astronomical tide.

Detailed explanation-5: -The major tidal constituent is the moon’s gravitational pull on the Earth. The closer objects are, the greater the gravitational force is between them. Although the sun and moon both exert gravitational force on the Earth, the moon’s pull is stronger because the moon is much closer to the Earth than the sun is.
