What are the causes of high tides, and how are the phenomena of high and low tides caused?

This difficult topic has been analyzed since ancient times, and the ancient Greek philosopher Plato believed that the earth, like man, must breathe, and the tides are the breath of the earth. After discovering the law of gravitation, Newton proposed the hypothesis that tides are caused by the magic of the moon and the sun on seawater, and scientifically explained the reason for the occurrence of tidal gestation. The sea water rotates with the rotation of the earth, and the rotating objects are subjected to centrifugal force, which makes them tend to leave the center of rotation, just like a rotating open umbrella, and the water droplets on the umbrella are about to be thrown out.

At the same time, seawater is also affected by the magic of the moon, the sun and other celestial bodies, because the moon is closest to the earth, so the moon has more magic. In this way, the seawater forms a tidal attraction under the combined action of these two forces. 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.

The moon is cloudy and full, so the time of high tide will continue to change, and there is an old saying that flowing water does not rot, and the sea is more than who can let him flow? Only gravity allows him to flow, and the tides are, in layman's terms, influenced by the moon, and the global transfer of sea water, some from the eastern hemisphere to the western hemisphere, some from the southern hemisphere to the northern hemisphere, more here and less there, and there is no more water in the world, no less, more here, less there, but in different forms.

Trouble, thanks!

What causes high and low tides?

Introduction: Those who live by the sea will find that the tide changes several times a day, there will be high and low tides, and it is because of the high tide and low tide. Some people will find on the coast, and there are many shells or fish tidal phenomena that cannot return to the sea in time due to low tide, which refers to high tide and low tide.

It often occurs in coastal areas, so what are the causes of high and low tides?

In fact, it is mainly due to the gravitational effect of the moon and the sun. Gravitational force occurs in two objects with mass, the sun has a gravitational attraction to the earth, and the moon also has a gravitational attraction to the earth, when the distance changes, the magnitude of the natural gravitational force will also change, and the sea water will continue to ** or fall under the action of gravity. In the morning, if the sea is called tide, in the evening if the sea is called thin, this is the name of the tide.

The high tide and low tide in the tide are caused by the gravitational pull of the moon, because the moon revolves around the sun, when the two rotate to a certain stage, the gravitational force will change, and at this time, the water surface on the earth will change accordingly, so the high tide and low tide will be formed. And the earth is not a circle, but an approximate ellipse, so when the moon turns to the vicinity of the earth, a high tide will be formed, and when the moon turns to the north and south poles of the earth, a low tide will be formed.

First of all, the high tide and low tide will affect people's daily work and rest for ordinary people, when the tide is high, you should stay away from the beach, and when the tide is low, you can quickly collect and fish. Moreover, tidal energy is also a kind of renewable energy, which can also generate electricity by itself through changes in the water surface, so the high tide and low tide are worth studying, and it can also bring a lot of scientific research and innovation to human beings. People at the beach often catch the tide, in fact, they take advantage of the high tide and low tide.

It's the gravitational pull of the moon and the sun, because gravity makes the sea have this phenomenon, and it's a very spectacular phenomenon.

It has to do with the gravitational pull of the Moon. This force is also known as tidal force, which is very common.

Because both the sun and the moon have a gravitational pull, the phenomenon of high tides and low tides is formed.

The gravitational pull of the moon is related, so the image of the ebb tide appears.

The reasons for high tide and low tide are as follows:

1. One of the reasons for the daily high tide and low tide of the sea: the rotation of the earth.

To put it simply, tidal force is an object due to the existence of its own volume, the distance between the points on the body of the object and the gravitational source is different, and this leads to the different magnitude of the gravitational force at each point.

2. One of the reasons for the daily high tide and low tide of seawater: gravitational interference of external celestial bodies.

The reason for the formation of ocean tides is the gravitational force of the heavens. The gravitational force is the difference between the gravitational pull of the Moon, the Sun, or other celestial bodies on an object of unit mass on Earth and the gravitational force of an object of unit mass on the center of the Earth. Therefore, both the magnitude and direction of the gravitational force on Earth vary from time to time and from place to place.

Sun-induced tides:

Because the Earth is in the orbit of the Sun planet, it is similar to the large water balloon demonstrated in the space lecture, that is, the Earth is weightless to the Sun. Weightlessness makes the Earth immune to the gravitational pull of the Sun, so that the Sun does not exert tidal forces on the Earth.

However, the diameter of the earth is 12,700 kilometers, so the difference in orbit altitude is 12,700 kilometers, so the vector parameters of the equilibrium point are different, and this difference causes the earth on the solar side to produce a slight tidal force phenomenon.

The main reason for the high tide and low tide is related to the movement of the moon and the sun, the principle is that the moon and the sun have a gravitational pull on the earth, that is, the tidal force.

Whereas, tidal force is an integral force, which is not completely determined by the magnitude of the gravitational force, but because the gravitational force experienced by different parts of the earth is not exactly the same magnitude and direction, so there will be a force difference and a direction difference, and these two "differences" will cause the tidal force.

Since the summer calendar is based on the change of the moon phase, it has a major function of reflecting the tides, and the tidal phenomenon is dominated by the moon, and the summer calendar based on the change of the moon phase is a guide to maritime activities in ancient times.

The Moon is attractive to the Earth's seawater, and the points on the Earth's surface are different from the Moon, and the place facing the Moon is gravitationally strong, and the seawater expands outward; The place with the back to the moon is less gravitational, and the centrifugal force becomes larger, and the sea water expands to the place with the back to the moon under the action of centrifugal force, and the tide will also occur.

The main reason for high and low tides is the gravitational pull of the moon. The gravitational force of the earth's particles by the lunar particles is the centripetal force of the earth's particles moving in a circular motion around the common center of mass, and the inertial force corresponding to this centripetal force is in the opposite direction of the magnitude of the centripetal force.

If the "object" is the sea water here, then there will be high tides here. In the same way, the gravitational pull of the Moon on the object is less than the corresponding inertial force, and their resultant force is opposite to the direction of the Earth's gravitational force on the object here, which also makes the gravitational force of the object significantly smaller.

High tide is the phenomenon of rising sea water due to changes in the water level of the ocean. There are three main reasons for this:

1. The gravitational effect of the sun and the moon on the seawater: The gravitational effect of the sun and the moon on the earth will cause the sea surface to fluctuate at a certain height and form tides. On the Earth's surface, tides affect coastlines to varying degrees at different times, causing the water to rise from low to high.

2. Changes in atmospheric pressure: atmospheric pressure has a certain effect on seawater. As the weather changes or the weather system moves, the pressure of the seawater also changes, resulting in the high or low tide of the seawater.

3. Wind effect of seawater: Wind can affect the flow and rise and fall of seawater. When the wind is strong, it pushes the sea water and causes it to move in the direction of land, so high tides may occur near the coastline, especially in weather conditions such as storms.

In summary, the main causes of high tides are the gravitational effect of the sun and moon on seawater, the change of atmospheric pressure, and the wind effect of seawater.

High tides are a phenomenon that occurs due to the gravitational pull of the moon and the sun on the tides on Earth. There are two main reasons for this phenomenon:

1.Lunar gravity: As the lunar spine orbits the Earth, the gravitational force causes a strong tidal force on the Earth.

This gravitational pull pulls on the ocean's water column to form a tidal wave that follows the position of the Moon. When the tidal wave accumulates to a high enough degree, the phenomenon of high tide is formed. In addition, due to the rotation of the Earth, the gravitational attraction will vary from region to region at different times, which leads to differences in the timing of high tides in different locations.

2.Solar gravitational pull: Although the gravitational pull of the sun has a relatively small effect on the earth, it also contributes to tidal phenomena.

When the Earth, the Moon, and the Sun line up in a straight line (as during a new moon and a full moon), the Sun's gravitational pull enhances the tidal effects caused by the Moon's gravity, resulting in greater high tides.

Therefore, the phenomenon of high tides is mainly due to the combined action of the gravitational pull of the Moon and the Sun. The timing and height of high tide in different regions are affected by factors such as topography, seafloor topography, and the rotation of the Earth.

The action of the Moon and the Sun on the gravitational force of the ocean is responsible for the rise and fall of the sea.

Although the gravitational force (or tidal force) that causes the rise and fall of sea water is caused by the gravitational pull of the sun and the moon, it is not the absolute gravitational force of the sun and the moon, but the difference between the gravitational force of the attracted object and the gravitational force of the center of the earth. The gravitational force is directly proportional to the mass of the tidal object and inversely proportional to the cube of the distance from the object to the Earth.

Because the mass of the Sun is 27023369 times the mass of the Moon, and the average distance between the Sun and the Earth is 389 times the average distance between the Moon and the Earth, the gravitational force of the Moon is twice that of the Sun, thus mechanically proving that the tides are indeed mainly caused by the Moon.

The volume of the earth is very large, the object on the ground closest to the moon, the orbital radius of the circular motion around the common center of mass of the earth and the moon is obviously smaller than the orbital radius of the earth's mass point, the gravitational force of the moon will be greater than the corresponding inertial force, these two forces can no longer be canceled, and the resultant force is opposite to the direction of the earth's gravitational force of the object, so that the gravity of the object becomes significantly smaller, then there will be a high tide here.
