Tidal phenomenon
A natural phenomenon called tides occurs for the waters of the seas and oceans, and this phenomenon depends on the centrifugal force, and this force has several combined effects resulting from the gravitational forces between the moon and the sun, and the Earth’s rotation around its center, and they are consecutive in occurrence, that is, when the tides occur, they are immediately followed by the occurrence of tides And in the phase of the occurrence of the tide, the sea level begins to gradually rise little by little, while in the islands the exact opposite occurs, the water level gradually decreases, and it is possible to repeat the phenomenon of the tide twice a day for some beaches, and this phenomenon is called the phenomenon of the half-day tide, and in another phenomenon The tide occurs once, and this is the natural type, and it is called the daily tide, and the third type is the mixed tide, in which two different ebbs and flows occur on the same day, and what most affects the tidal phenomenon is the amplitude of the tidal phenomenon, which is considered the maximum amplitude of the wave or the amount of its displacement And that depends on the position of the sun in relation to the moon, and it is also affected by the extent of the depth of the waters of the ocean, in addition to the trajectory of the waters of the seas and oceans. Haitat has a role in this, and the shape of the coastline has an impact on the phenomenon.
How it happened
The tides reach their highest level when the moon is full, that is, when it becomes full, in the middle of the month, and this phenomenon is at its lowest level when the moon is in full moon, and the effect of the tides reaching its highest level at the full moon is that the moon’s gravitational force is intense in this period temporal, and the sun plays an important role in regulating the process of the occurrence of tides, so when the sun and the moon are on one straight line, the tide reaches its highest level, due to the force of attraction of the sun along with the force of attraction of the moon, and in this case the tide is high, but if the location of the moon and the sun They are stationed along the two sides of a right angle with respect to the earth, so the gravitational force of the moon is stronger than the effect of the gravitational force of the sun on water bodies, and in the islands the water level decreases, so this case is called the tidal tides, and the tidal phenomenon occurs twice every 12 hours, after the passage of the earth during its rotation In front of the moon, the tidal phenomenon occurs in the water bodies on the surface of the earth facing the moon, and tides occur immediately after these places move away from the front of the moon.

- The phenomenon of tides is of importance to navigation.
- The phenomenon of tides helps to purify and cleanse the seas and oceans.
- It expels sediment from the mouths of rivers and ports and purifies it from it.
- Exploiting this phenomenon by generating environmentally friendly energy, which contributed to reducing the electrical load on thermal stations.
Tidal installations
These installations depend on the natural phenomenon of tides, as they result in solar and lunar tides, so the solar tides arise when the sun and the moon have an effect on the ocean waters, due to the sun’s gravitational pull on the Earth.
