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: -The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur.

Detailed explanation-3: -When the gravitational pull of the Sun and moon are combined, you get more extreme high and low tides. This explains high and low tides that happen about every two weeks.

Detailed explanation-4: -Tidal forces are changes in the gravitational potential energy of the Sun, Moon and Earth. These forces cause the periodic motion of the seas which create a temporary change in water levels that vary depending on location.

Detailed explanation-5: -The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides.
