How is the sea formed? How is seawater formed?

Research now proves that about 5 billion years ago, a number of large and small nebulae were separated from the solar nebula. They rotate while revolving around the sun. In the process of movement, they collide with each other, and some clumps combine with each other, from small to large, and gradually become the primitive earth.

During the collision of nebula masses, the sharp contraction under the action of gravity, coupled with the transformation of the internal radioactive elements, caused the primitive earth to be continuously heated and warmed. When the internal temperature reaches a high enough level, the substances in the earth, including iron, nickel, etc., begin to melt. Under the action of gravity, the weight sinks and tends to concentrate on the center of the earth, forming the earth's core; The lighter ones rise to form the earth's crust and mantle. At high temperatures, the moisture inside vaporizes and rushes out along with the gases and soars into the air.

But due to the gravitational pull of the center of the earth, they will not run away, and only around the earth, becoming a circle of air and water. A layer of crust located on the surface of the earth, in the process of cooling and condensation, is constantly impacted and squeezed by the violent movement of the earth's interior, so it becomes folded and uneven, and sometimes it is squeezed out, forming ** and volcanic eruptions, spewing out magma and hot gas. At first, this happened frequently, but gradually became less and less common and slowly stabilized.

This process of differentiation of light and heavy materials, resulting in great turmoil and great reorganization, was completed about 4.5 billion years ago. After the earth's crust has been cooled and shaped, the earth is like a long-left and dried apple, with a wrinkled and uneven surface. Mountains, plains, river beds, sea basins, all kinds of terrain are available.

There are low-lying places on the surface. Then the water accumulates. When there is more water, it becomes the sea.

The earth can be called a water ball, and about 3 4 of the area on its surface is the ocean, and there are other sources of water, but the sea water is the main body of the earth's water. Where does so much seawater come from?

At first, it was believed that this water was inherent in the earth. When the Earth condensed from the primordial solar nebula, it carried this part of the water. As the earth continues to change, this water, which was originally stored in minerals and rocks in the form of structured water, crystalline water, etc., is released and becomes the first of the seawater.

For example, volcanic activity always has a large amount of water vapor spilled out along with magma. Based on this, some believe that this water vapor is the "primordial water" released from the deep parts of the earth.

Astrogeological studies have shown that among the Earth's closest neighbors, whether it is Venus and Mercury which are closer to the Sun, or Mars which is farther away from the Sun, and even the Moon which is closest to the Earth are water-poor, only the Earth is blessed with so much water. Scientists have mixed accounts of this. Some believe that water on Earth is not inherent to Earth, but is brought by comets that crash into Earth.

Some small comets made up of ice masses rush into the Earth's atmosphere, and the meteorite ice is converted into comet water due to frictional heat.

Some scholars believe that Venus, Mars and the Moon originally had water, but because the mass of the Moon and Mars was too small and the gravitational force was too small, all the original water escaped; The surface temperature of Mars is too high to sustain the presence of water. Due to the moderate conditions of the earth, the original water can be preserved for a long time. It cannot be inferred from the current water-poor state of the Earth's immediate neighbors that the early Earth was also water-poor.

Chinese scholar Dong Miaosheng put forward the hypothesis that "there are many seasons in nature". According to this hypothesis, in the 4.6 billion years since the formation of the Earth, the biosphere has periodically moved from Earth to another planet, and then periodically cycled back to Earth like the return of migratory birds. This naturally includes several times when the sea water dries up and rises.

By using this hypothesis, we can solve the problem that the previous theories of "extraterrestrial water" and "inherent to the earth" have not been able to solve.

However, there is not enough scientific evidence on where the sea comes from, so where it originated remains a mystery.

The formation process of Pahui seawater:

1. The Great Year Brigade was on the primitive earth about 5 billion years ago, with the scorching sun in the sky and lightning and thunder; Lava rolls on the ground and volcanoes erupt. This natural phenomenon has become the "birth" of the origin of life. The huge heat energy promotes the fierce movement and change of various materials on the primitive earth, giving birth to vitality;

2. Due to the continuous heat dissipation of the primordial earth, the scorching surface gradually cooled down, and the water that originally ran from the earth to the sky condensed into raindrops, and then fell to the ground, which lasted for many hundreds of millions of years, forming the primordial ocean;

3. In the primitive ocean, the sea water is not salty, and the stool is acidic and oxygen-deficient. The water evaporates and rains on the terrain and falls back to the ground, dissolving the salt from the rocks on land and the seabed and collecting them in the seawater. After hundreds of millions of years of accumulation and fusion, it becomes more or less uniform saltwater, and this is how seawater is formed.

After the formation of the crust and mantle core, the interior of the earth will be squeezed in large quantities, and in the process of extrusion, the interior of the earth will also be in a high temperature state, so the earth will exude a lot of water molecules at that time. However, due to the drop in the earth's temperature, the surrounding water vapor circle turned into water droplets, which became more and more on the earth's crust, causing the earth to experience heavy rainfall for a long time. After heavy rains, the ocean is formed as the water accumulates and increases.

Due to the thin crust of the earth and the continuous bombardment of the earth's surface by small celestial bodies, magma is constantly spewing out, so the earth is a sea of firewater accumulation. The magma is accompanied by a large amount of gas and dust, which rises into the air and forms clouds. Small droplets of water in the clouds turn into rain.

After a long period of rainfall, a large amount of rainwater gradually accumulated in the low-lying areas of the original crust, forming an ocean.

Without any basis, a bunch of nonsense, unscrupulous, indeed a literate hooligan!

It's coming, it's coming, it's coming, it's all Li Lili.
