# How tides are created?

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).

Tides are formed due to the gravitational force exerted by the Sun and the Moon on the Earth. The Sun’s gravitational pull is much larger than the Moon’s, and the difference is important to the creation of tides. Tides are of two types: High and Low tides, which are based on the extent and position of the Sun and Moon.

The tides are the result of the moon exerting its gravitational force on the ocean and bulging it both toward and away from the moon. The tide is higher, the ocean is higher, at the location closest to the moon and on the opposite side of the Earth. As the Earth rotates, the position relative to the moon changes, so the bulge moves.

While I was researching we ran into the inquiry “How does the spin of the earth create tides?”.

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.

Gravitational pull exerted by one object, such as the sun or moon, that raises tides on another object, such as the Earth., and tide. Rise and fall of the ocean’s waters, caused by the gravitational pull of the moon and sun.

One way to think about this is the forces that generate the tides are: The gravity force of the moon. This force moves the water in the oceans toward the moon. A point P at the rotating surface of the earth will experience a varying water depth with two maximum (two high tides).7.3. Spring tide – Neap tide.

Tides are very long waves that move across the oceans. They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun. When the highest point in the wave, or the crest, reaches a coast, the coast experiences a high tide.

## How much time is there between tides?

So back to business; most places around the world will see two high tides per day, and two low tides per day; with approximately 6 hours of separation between each. There are some places that only get one cycle every 24 hours and there are a few very unusual places where the tidal pattern is both unique and irregular.

## Are tides higher when the Moon is directly overhead?

Tide-generating forces are also enhanced when the moon is directly overhead at the equator, part of a cycle lasting 27.2 days Spring tides are always higher at these times of year.
