The sea has tides, why don t the lakes have tides?

How are ocean tides formed on Earth? What we usually learn is that because the gravitational pull of the Moon acts on the Earth, it leads to an imbalance in the gravitational pull - the side of the Earth that is close to the Moon experiences the most gravitational pull of the Moon, while the side that is far away from the Moon has the least gravitational pull. The result is a stretch of the ocean that rises along both sides of the earth, eventually forming the tides.

However, this gravitational difference does not mean that the Moon "stretches" the oceans. If this is how ocean tides work, then why don't lakes, ponds, and the water in cups act tidally? In fact, many people misunderstand the root cause of tides.

Of course, tidal action is indeed caused by the uplift of the ocean along both sides of the Earth, but not directly by the poor gravitational pull of the Moon. So, what is the real cause of the uplift of the sea?

It is calculated that at any point on Earth, the gravitational pull of the Moon acting on the Earth is 10 million times weaker than the Earth's own gravity. As a result, the gravitational difference between the side of the Earth facing the Moon and the side facing away from the Moon is minimal. In fact, the Earth's tidal uplift is the product of a complex gravitational interaction between the Moon, the Earth, and the Sun.

While it is true that every drop of water on Earth is attracted by the Moon's gravitational pull, the effect of the Moon's gravitational pull at the molecular level is not obvious because the inward pull of the Earth's gravity is too strong. However, the point is that seawater makes up about 71% of the Earth's surface and that the world's oceans are connected, which allows the forces on each water molecule to add up to considerable water pressure.

Water molecules near the Earth's poles are pulled primarily towards the Earth's center of gravity (near its core), and the water molecules closest to the Moon (at the Earth's equator) are subjected to the strongest lunar gravitational pull. At the same time, the water molecules farthest from the Moon are subjected to the weakest gravitational pull.

Since water molecules can easily collide with each other, the macroscopic manifestation of these countless tiny collisions is to squeeze seawater away from the poles. This global water pressure defends the Earth's gravity, forming two uplifts – the tides. Therefore, the seawater is not directly uplifted by gravitational stretching.

The ocean rises in the direction of the Earth-Moon, which is like squeezing a water-filled balloon by hand, and its sides will bulge.

For smaller bodies of water, such as lakes, there are no significant tidal uplifts because they lack enough water to generate water pressure that can significantly overcome the Earth's gravity.

In addition, the gravitational pull of the sun also affects the tides, accounting for about one-third of this phenomenon. When the Sun's gravitational pull cancels out the Moon's, it results in a below-average tidal wave. When the sun is in a straight line with the moon, a high tide is triggered.

Because no lake can span the globe, it can't. Even though the water of the lake is subjected to the gravitational pull of the Moon, the gravitational pull of the Earth makes the net force of the water 0. The oceans are different – the ocean's global tides (the gravitational potential energy of the seawater) can be maintained, and the water on one side of the earth goes down, and the water rises on the other side of the earth.

It has nothing to do with the quality of the water in the lake, if there is a lake that spans the whole world, then it must have tidal phenomena. A lake without tides is a closed lake.

Tides are caused by the gravitational pull of the moon.

The mass of the sea is very large, and the gravitational pull is great, and the lake is small compared to the sea, and the gravitational force is very small, so there is no tidal phenomenon.

Tides vary from place to place, and different regions often have different tidal systems, all of which derive their energy from deep-sea tide waves, but have their own unique characteristics. Despite the complexity of the tides, it is possible to make accurate forecasts for tides anywhere. Ocean tides derive energy from the rotation of the earth and slow down the rotation of the earth in the process of absorbing energy.

But this slowing down of the Earth's rotation is almost imperceptible in the lifetime of man, and it is not accelerated by the exploitation of tidal energy. This energy is dissipated at a rate through friction between the shallow sea and the coastal zone. It is possible to extract energy from the tides only when there are high tides, energy concentration, and in places where the geographical conditions are suitable for the construction of tidal power stations.

Three main reasons for the formation of the Dead Sea:

Temperatures in the Dead Sea range range from an average of 34 °C in summer to a maximum of 51 C° in summer and 14 to 17 °C in winter. The higher the temperature, the greater the evaporation, and the water of the Dead Sea is constantly evaporating.

It is dry and rainless, with an average annual rainfall of only 50 mm and evaporation of about 1,400 mm. With more sunny days, stronger sunshine and less rain, the replenishment of water is negligible, and the Dead Sea is becoming more and more "thick" – more and more minerals are deposited at the bottom of the lake, and the salinity is increasing.

Before the Jurassic and Cretaceous ditches were formed, a large area of the Mediterranean Sea covered Syria and Palestine. In the Miocene, the seabed was uplifted, resulting in the uplift structure of the Transjordan Highlands and the ** Palestine Mountains, and the cross-section of the Dead Sea depression appeared. The movement between the plates caused faults to form on the surface of the earth, allowing the Dead Sea to form.

The gravitational pull of the Moon causes a gravitational pull towards the Moon on the Earth's surface, and it also causes a gravitational pull towards the Moon on the surface of the Earth's oceans. When these two forces interact, a tidal wave is formed.

Tides refer to the phenomenon of periodic fluctuations in the water level in the ocean. It is one of the most significant cyclical phenomena in the ocean, and it is also one of the important marine resources and environmental conditions for human beings. So, why are there tides? Let's take a look at the reasons for the formation of ocean tides.

Tides are caused by the gravitational pull of the Earth and the Moon. The gravitational pull between the Earth and the Moon causes periodic fluctuations in the ocean surface. The gravitational pull of the Moon is more significant than that of the Sun, because the Moon is closer than the Sun, so its gravitational pull on the Earth is greater.

The effects of the Earth's rotation.

The influence of the terrain.

The gravitational cavity of the Moon causes a gravitational pull towards the Moon on the Earth's surface, and it also causes a gravitational pull towards the Moon on the surface of the Earth's oceans. When these two forces interact, a tidal wave is formed.

The rotation of the earth also has a certain influence on the formation of tides. Because the speed of the Earth's rotation is constant, and the Moon's cycle around the Earth is about 28 days, the tides on Earth occur twice a day. The time interval between these two tides is about 12 hours.

Topography also has an influence on the formation of tides. Tides in the ocean can be affected by the terrain of land and seabed. If there is a narrow channel or shallow terrain in the ocean, it will affect the ebb and flow of the tide.

In some places, the tides are more pronounced than in others due to the topography.

Gravitational action of the Earth and the Moon.

In conclusion, tides are periodically ebb and flow water levels in the oceans, caused by the gravitational pull of the Earth and the Moon. The Earth's rotation and topography can also have a certain hail effect on the tides. Understanding the causes of tides is important for the use of tidal resources and the protection of the marine environment.

Tides refer to the phenomenon of periodic fluctuations in the water level in the ocean. It is one of the most significant cyclical phenomena in the ocean, and it is also one of the important marine resources and environmental conditions of the manhood sail resistant category.
