Why do the oceans have high and low tides? How does it work?

Because it is affected by the gravitational pull of the sun and the moon, the phenomenon of high tide and low tide is formed. The principle is that when the ocean faces the moon, it is affected by the gravitational pull of the moon, so the phenomenon of high tide is formed.

The ebb and flow of the tide of the sea is a natural phenomenon, and the tides are related to the movement of the earth. Tides are created due to gravitational changes between the Moon and the Earth.

Because the Earth is affected by the gravitational pull of the Moon, the Moon forms high tides and low tides in the process of orbiting the Earth.

Generally speaking, the side facing the moon on the earth is affected by the gravitational pull of the moon, so the water will rise, and the side carrying the moon will rise because the moon has the smallest gravitational pull on it to the center of the earth, and the water will also rise, which is the high tide, and the place perpendicular to the center of the moon is the lowest, which is the low tide.

Due to the action of the tidal force of the sun and the moon, the periodic movements and changes in the earth's lithosphere, hydrosphere and atmosphere are collectively called tides. The elastic-plastic deformation of the solid earth caused by the action of the sun and moon tidal force is called the solid tide, referred to as the solid tide or the ground tide, and the periodic rise, fall and advance and retreat of the sea surface caused by the sea water under the action of the sun and the moon tidal force is called the ocean tide, referred to as the ocean tide, and the periodic changes of various elements of the atmosphere by the action of the gravitational tide are called atmospheric tides, referred to as air tides.

Among them, the atmospheric tide caused by the sun is called solar tide, and the solar tide caused by the moon is called the solar tide. Because the Moon is closer to the Earth than the Sun, the ratio of the gravitational force of the Moon to the Sun is 11:5, and for the ocean, the solar tide is more significant than the solar tide.

The driving force of earth tides, ocean tides and air tides is caused by the different gravitational forces of the sun and the moon on various parts of the earth, and the three affect each other.

We are familiar with the ocean, it is the treasure house of our human nature, every year to provide countless seafood, for the development and spread of human civilization has made a great contribution, we know the ocean, it has high tide and low tide, why does the sea rise and fall? What causes it? How does it work?

The high tides and low tides and the moon are related to the sun, and their gravitational pull will cause high tides and low tides, just as the gravitational pull of the earth on us will also be affected by the gravitational pull of the moon and the sun.

People who live by the sea know that the high tide is terrible, many tourists who come and go see the high tide and do not move, and finally be beaten by the big waves to know that the danger is coming, and the low tide will bring a lot of seafood products, because many crabs or fish have no time to retreat, they will be stranded on the beach or in small puddles, and the reason for the high tide and low tide is the gravitational pull of the sun and the moon, if the Pacific Ocean is facing the moon, it will be subject to a great gravitational pull to cause high tide, and when the moon goes to the other side, it will trigger low tide, The sun and the moon are similar in that principle.

For the ocean we should "respect", not only grateful for its gift but also for its mystery, our current technology can dive up to about five thousand meters, but the ocean is unfathomable, according to the exploration of the deepest trench up to tens of thousands of meters, what creatures live in it still do not know, many people speculate that there are "monsters" but before everything is confirmed, it is right to be respectful and grateful.

Why does the sea rise and fall and what are the main reasons? After reading it, I understand.

The high and low tides of the sea are caused by the moon, a phenomenon called the siphon principle, which occurs due to the distance of the moon from the earth.

The high and low tides of the sea are caused by the gravitational pull of the Moon. The high tide and low tide are caused by the gravitational pull of the moon, and the principle is that the gravitational force of the moon at high tide and low tide is different.

The high tide and low tide of the sea are caused by the autobiography of the earth, when the earth rotates to face the moon, the closest distance is pulled up by the gravitational pull of the moon to form a high tide, and naturally the sea water on the other side of the earth will flow to the place where it is pulled to form a low tide.

The gravitational pull of the Sun and the gravitational pull of the Moon form the tides.

The high and low tides of the sea are the result of the gravitational pull of the Moon. The Moon's gravitational attraction to the Earth's seawater is different when it is relative to different positions on the Earth, resulting in high tides and low tides in the seawater. The tidal principle can explain this phenomenon.

At all times, seawater is in equilibrium with the horizontal components of the shadow tidal forces, gravity, and pressure gradient forces. That is to say, when the sea water is affected by the horizontal force component of the tidal force, in order to maintain the original equilibrium period, the sea level must be inclined relative to the original stationary sea surface, and at the horizontal component of the tidal force and the bifurcation point at the north and south ends, the accumulation and loss of sea water is the most, which also promotes the formation of tidal phenomena. Of course, some people say that the essential cause of the formation of tides is not the gravitational effect of the moon, but the transformation of the celestial mass center, but the current discussion on this aspect has not reached a unified conclusion, so people still generally regard the tide theory analyzed in Newton's works as the mainstream.

After low tide, high tides can form elsewhere on the surface of the sea. The tidal phenomenon is a natural phenomenon in coastal areas, which is related to both the Sun and the Moon, and is mainly caused by the gravitational pull of the Moon. The moon revolves around the earth all the time, so no matter what the moon turns to, the waters in the ocean will converge.

The high tide and low tide of sea water are mainly related to the gravitational attraction of the moon and the sun, and the earth is affected by the gravitational force of the sun and the moon, and the low tide and high tide will occur; The water comes from the place where the grass falls, and the sea water rises and falls, so at high tide the water flows over at low tide.

The high and low tides of the ocean are caused by the gravitational pull of the moon on the seawater. It came from the place where the tide was low.

The tidal phenomenon of the Earth's oceans is mainly caused by the Moon, and the Moon's gravitational pull will slightly "suck" the water of the Earth's side facing the Moon away from the Earth's surface, so that a high tide is formed here. In this case, the water from other ocean areas of the planet will rush in, and at the same time, the areas that have lost some of their water will form a low tide, and the low tide water will actually go to the high tide area of the ocean.

Mainly because of the law of the sea, there will be tidal phenomena, which will cause such a situation according to the gravitational pull of the sun and the moon. The water at high tide is exchanged because the water on Earth is affected by gravity.

The reason why the ocean rises and goes down is actually related to the gravitational pull of the moon and the sun, which is caused by them, which is a very normal phenomenon. The water at high tide generally comes from the sea.

Friends who live next to the sea may be very familiar with the high tide and low tide, and can even know exactly when the sea rises and falls. Have you ever wondered why the sea rises and falls? Why is there still a high tide on the sea surface when there is no wind and waves?

After every ebb and flow, where does all that sea go?

In fact, the ebb and flow of the sea is a cyclical phenomenon that is necessary every day, and people call it a tidal phenomenon. In ancient times, people were very curious about this phenomenon, when the sea water was facing the moon, the wild force was the greatest, and the sea water would be attracted to expand outward. Although the square facing away from the moon is subject to a small gravitational pull of the moon, it is subjected to a large centrifugal force on the earth, so it will also expand outward.

In this way, the distribution of the oceans on the Earth's surface is elliptical, but because the Earth is constantly rotating, this change in water level also becomes periodic.

After understanding the reasons for the formation of tidal phenomena, many people will wonder if the amount of sea water that goes after the tide goes down**, will it reduce the amount of sea water on the earth? The newcomer can pay attention to it, and according to a few aspects, you will not miss the wonderful content after browsing the network period. In fact, you don't have to worry, no matter how the sea rises and falls, the total amount of sea water on the earth's surface has basically not changed, and the sea water that recedes at the ebb and flow actually flows to places with greater wildness.

You know, the world's oceans are connected, just like the principle of flowing down, where the gravitational pull is strong, the sea water will also be sucked over, forming a high tide in another place.

This phenomenon has been seen as a threat in the eyes of people before, because it has only caused damage to people, especially for fishermen who go out to sea to fish. However, with the continuous development of science and technology, human beings will not be able to control the tide of electricity and water as a treasure, which is the famous tidal power generation, which will provide more electricity and communication to human beings.

It is precisely because of this tidal phenomenon that many people like the sea and like its waves. However, it is not difficult to see from the tidal phenomenon that the earth's natural environment is actually affected by the entire solar system and even the universe. If we want to make our home last longer and protect the environment, we should start with the individual.

The gravitational pull of the earth causes the tide of the sea to rise and fall. The water flows underground, then evaporates and returns to the ocean.

The gravitational force on the earth is not the same, and the sea is very large, so the gravitational force generated is also different. That's why the tide rises and falls. After the tide recedes, the waters return to the sea and calm again.

I think that the principle of the high and low tides of the sea is a natural phenomenon, and the sea water after the tide recedes is returned to the sea.

The ebb and flow of the tide is caused by the gravitational pull of the moon and the sun on the seawater, the sea water at high tide is from the sea water from the other hemisphere, and the sea water at low tide goes to the sea water from the other hemisphere.

The ebb and flow of the oceans is caused by the gravitational pull of the Moon. The sea water at high tide comes from the sea at low tide, and the sea water at low tide comes from the sea at high tide.

It is mainly the gravitational pull of the moon that causes the tide to ebb and flow, and the sea water comes from the sea at high tide and retreats into the sea at low tide.

The high tide and low tide of the sea are caused by the gravitational pull of the sun and the moon, and the main action is the gravitational pull of the moon.

The high tide and low tide of the sea is a natural phenomenon. At high tide, the sea rolls in waves**, the scene is spectacular, and at low tide, the water quietly recedes and re-emerges on the beach, with high and low tides usually occurring twice a day.

"Tide" is a phenomenon in which the rise and fall of sea water occurs during the day, and the rise and fall occurs at night, which is called "tide", so people are also collectively called tides. In ancient Chinese books, it is said that "the water of the sea is born as a tide, and the evening is born as a tide". Between high tide and low tide, the water level does not rise or fall for a period of time, which is called flat tide.

The gravitational force of the Moon causes not only the tides of the ocean, but also the atmospheric tides of the atmosphere. However, the first movement of the atmosphere is relatively small, so I did not feel it.

Introduction to Tide Types:

1. Cross-tide.

In Dingqiao Town, Haining City, there is a large gap 55 kilometers away from Hangzhou Bay, which is an excellent location for the cross tide. Due to the long-term sediment accumulation, a sandbar is formed in the middle of the river, which divides the tidal wave from Hangzhou Bay into two streams, namely the east tide and the south tide.

2. A line of tide.

The best place to watch the first line of tide is located in the tide viewing resort park in Yanguan Town, Qiantang River, which was once the fortress of Haimen in Yanguan Ancient Town, and is the key point connecting the city and the seaside. Looking at it from afar, the white line on the Qiantang River turned into a white ribbon and floated slowly, and a burst of rain also came with the wind.

Because the earth and the moon are constantly moving, the relative positions of the earth, the moon and the sun are changing periodically, so the gravitational force is also changing periodically, which makes the tidal phenomenon occur periodically, which is the reason for the ebb and flow of the tide.

Seawater also rotates with the rotation of the Earth, and the rotating objects are subjected to centrifugal force, which makes them have a tendency to leave the center of rotation: at the same time, seawater is also attracted by the Moon, the Sun and other celestial bodies, because the Moon is closest to the Earth, so the attraction of the Moon is greater. In this way, the seawater forms a tidal attraction under the combined action of these two forces.

The Moon, commonly known as the Moon, also known as Taiyin and Xuantu in ancient times, is the only natural satellite of the Earth and the fifth largest satellite in the solar system.

The sun is the central body of the solar system and occupies the overall mass of the solar system.

Earth (English name: earth; Latin: Terra) is the third closest planet to the Sun and the only known object that harbors and supports life.

It occurs because of the gravitational force of celestial bodies.
