The origin of the ocean. After a careless interstellar traveler quickly passed by the earth in the distance, he might record in his voyage log, "A strange star that seems to be composed purely of water. It is recommended that when returning, arrange Detailed observation around the Earth. "In the vast universe that we can observe, it is not uncommon to find a little trace of H2O on a certain planet, but water covers 71% of the earth's area and the total volume is about 1.4 billion cubic kilometers. Existing in such a large amount, this can only be described as a miracle. Where does water on Earth come from? Is it inherent in the human mind? no. Is it produced by human practice? Neither. --The water on earth falls from the sky. Regarding the source of water on the earth, scientists used to believe that the source of water is the interior of the earth, which was naturally produced when the earth was formed. This type of theory is riddled with loopholes, limitations, and difficulties, and is rarely taken seriously these days. American scientists recently proposed an eye-catching new theory: the water on Earth comes from comets made of ice from space. This theory is correct in looking outward, but when it comes down to icy comets, it will cause many problems. For example, it cannot explain why the earth alone among the nine planets has become a "magnet" for massive icy comets? The Earth's water was indeed placed on the Earth by some force, and the atmosphere held it in place through the atmospheric water cycle. If only water was placed without an atmosphere, no matter how much water there was, it would have been lost in space long ago. This is an extremely sophisticated design. The amount of water in the earth's hydrosphere may not have been so much initially, and the area of ????the oceans was not as large as it is now. The land at that time should have been widely exposed and connected together. Later, the outer hydrosphere of the earth broke up, and more than 2-3 times the amount of water should have been added to the earth's hydrosphere. The seawater flooded the land, and Pangea was divided into continents, which formed the current pattern of the earth's surface. The outer hydrosphere now no longer exists, leaving us with no way of knowing its exact design. But based on the laws of physics we know and the research methods we have today, we can use computer models to simulate and restore the living environment and strange landscapes on the earth at that time. The model will be very complex. For example, is the outer hydrosphere discrete or continuous? Does water exist as a super-dense liquid, or is it a mixture of liquid water, ice particles, and dust particles like Saturn's rings? If the outer hydrosphere rotates synchronously with the Earth, what is its minimum orbital altitude? (For those who are only kindergarten teachers and have not studied high school physics or calculus, this question is optional) Due to the tilt of the earth's rotation axis, what kind of pattern will there be in the circulation system caused by the uneven heat density of the outer hydrosphere? What impact does the circulation system have on the climate system? Is it to make the world feel like spring all year round, or is it to make the environment suitable for human survival limited to a narrow ancient civilization belt called a large river basin? At the beginning of ancient times, who preached it? The upper and lower parts have no form, so how can we examine them? Between darkness and darkness, who can be the best? How can we recognize the image of Feng Yiwei? Light and dark, but what is time? What is the origin and transformation of the Yin and Yang triad? What does the sun look like under a hydrosphere canopy? Is the sky still blue? Is there any strange celestial phenomenon as magnificent and mysterious as the aurora? Is it completely dark at night? If the sky changes from purple to red every day instead of a gentle blue, what will be the emotions of people living under it? What kind of world view will people have, and will they build a civilization of superior species or inferior species? . . . As long as I am given enough scientific research funds and a suitable research team is formed, it is completely possible to establish such a model. Questions about the outer hydrosphere must be answered systematically using such theoretical models. Instead of simply affirming or denying a certain issue by patting your head. Anyone with a modicum of scientific training should know this way of thinking. The question is who will provide the funding? There are people funding the study of differential geometry in high-dimensional space, and there are people funding the study of black hole physics, but I can’t think of any government or company that is willing to fund research on epihydrosphere. Unless the US government decides to implement the plan to rebuild the sky in order to save the earth's environment. However, I suddenly thought of a possible sponsor, Hollywood! If Hollywood can be persuaded to make a blockbuster based on the flood of Noah's Ark, for example, using the clichés of "Titanic" or "Pearl Harbor", it will film a pair of Noah's neighbors in the year when the outer water circle burst. The first love story of a boy and a girl who has just entered puberty is bound to be a good box office hit. Of course, the film's vivid presentation of the strange landscape of the Earth under the canopy of the outer hydrosphere is also an important selling point, especially the spectacular final shot of observing the collapse and collapse of the Earth's outer hydrosphere from outer space. There must be an IMAX version. If Hollywood were to make this movie, then it would be a piece of cake, a piece of cake, to fund $8 million to 10 million in pre-production research on epihydrosphere in order to recreate the outer hydrosphere sky with a basis. The capitalists made money, the people were entertained, and science took the opportunity to advance. More than 2/3 of the earth's surface is covered by water, so the earth is called the water planet. So where does the water on the Earth's surface come from? There are currently two explanations for this. One idea is that water comes from the earth itself. When the earth condensed into a planet from the original nebula, a large amount of hydrogen and oxygen were released from the earth's interior; coupled with the particle flow emitted by the sun, hydrogen and oxygen were also brought to the earth.

These gases react chemically to form water. Another part of the water comes from dehydration of minerals inside the earth's crust. Another view is that water comes from outside the earth and was captured from space when the earth was formed. When meteorites containing water condensed to form the Earth, the water was trapped in the structure of the Earth's interior material. In the future, as the temperature of the earth increases, the rotation speed accelerates. Under the action of the centrifugal force of the earth's rotation, light and active water is squeezed out of the earth's surface and becomes water vapor. It then condenses to form precipitation and falls to the ground, thus forming surface water. Both statements require further scientific exploration to make a judgment.
