How did the mountains and water of the earth come from, and how did the water of the earth come from

Mountains: Formed by the action of internal and external forces of the earth. Such as: plate extrusion, fault development, external erosion, etc.

Water: A large number of debris made of an aging planet**, which is mostly inorganic salts and the like, and contains many water molecules inside them, the so-called crystalline hydrates. The crystalline water in the crystalline hydrate is separated by the high temperature in the earth's interior and becomes water vapor.

When the water vapor sprayed into the air reaches saturation, it cools into clouds, turns into rain, falls on the ground, gathers in low-lying places, gradually accumulates into lakes and rivers, and finally collects in the lowest areas of the surface to form the ocean.

Taiji gives birth to two rituals, two rituals give birth to four elephants, and four elephants give birth to gossip ,..Eventually, there was everything.

From the perspective of our geological community, mountains are the product of tectonic movements, and water is inherent as a substance.

One of the sayings is: mountains are mainly formed by the internal forces of the earth, that is, the crustal movement is formed, and the crustal movement is divided into several types, which are the specific ones, forget! As for water, most of the original water was brought by asteroids, that is, those planets in the form of solid water, when they hit the earth, they also brought water, and at the same time hit the earth, the water inside the earth was excited, but only a small part, mainly foreign accounted for the majority of the part.

The most representative of the earth's water is the "exogenous theory" and the "self-source theory". 1. The exogenous theory holds that the composition of comets that collide with the earth and meteorites that land on the earth contains a certain amount of water, generally as high as 10% or more. Among them, carbonaceous chondrites have more water.

Chondrites are one of the most common meteorites in the solar system, accounting for about 86% of all meteorites. Meteorites that descend on Earth carry moisture to Earth. <

The most representative of the earth's water is the "exogenous theory" and the "self-source theory".

1. The autologous theory holds that when the earth originated, the magma deep underground contained abundant water, and under the right conditions, the water in these rocks would be released. In the first few hundred million years after the formation of the earth, due to the thin crust and the continuous bombardment of the earth's surface by small celestial bodies, molten magma in the mantle was prone to upwelling and erupting, so the earth at that time was full of fire. Along with the magma, there is also a large amount of water vapor and carbon dioxide from the dates, which rises into the air and envelops the earth.

Water vapor forms clouds, which produce rainfall. After a long period of rainfall, in the low-lying areas of the original crust, water continues to accumulate, forming the most primitive ocean. The water of the pristine sea was only slightly salty, and only later did the salinity gradually increase.

It was through the gradual increase in water volume and salinity, as well as the vicissitudes of geological history, that the pristine ocean gradually formed the ocean of today.

2. The exogenous theory holds that comets that collide with the earth and meteorites that fall to the earth contain a certain amount of water, generally as high as 10% or more. The carbonaceous chondrites in the bench bridge contain more water. Chondrites are one of the most common meteorites in the solar system, accounting for about 86% of all meteorites.

Meteorites that descend on Earth carry moisture to Earth. In addition, some people believe that the solar wind reaches the upper layers of the earth's atmosphere, bringing a large number of atomic nuclei such as hydrogen, carbon, and oxygen nuclei, which combine with electrons in the atmosphere to form hydrogen atoms, carbon atoms, oxygen atoms, etc. It is then transformed into water molecules through different chemical reactions.

There are generally 2 theories about whose ** is on the planet.

The "Exogenous Theory", as the name suggests, holds that the water on Earth comes from outside the Earth. Mainly comets and water-rich asteroids that carry a lot of ice components. Comets, which are made up of water and interstellar dust, bring a lot of water with a comet hitting the Earth.

Some water-rich asteroids descend on the earth to become meteorites, which also contain a certain amount of water, generally, some can reach more than 10%, of which carbonaceous chondrites contain more water. Chondrites are one of the most common meteorites in the solar system, accounting for about 86% of all meteorites. For this reason, some scientists believe that it is extraterrestrial bodies such as comets and asteroids that bring their frozen water resources into the Earth's environment when they hit the Earth.

"Self-origin theory" holds that the water on the earth comes from the earth itself, and the earth is formed by the fractionation, collapse, and condensation of the original sun, nebula, gas, and dust. When the earth originated, the material that formed the earth contained water. At the time of the formation of the earth, the temperature was very high, and water was either present in the earth's crust, mantle, or gaseous state in the earth's atmosphere under high pressure.

Later, as the temperature dropped, the water in the Earth's atmosphere condensed and fell to the ground. The water in the magma is also released into the atmosphere and to the surface as a result of volcanic eruptions and geological activity. The water that collects into the low-lying areas of the earth's surface forms rivers, lakes, and oceans.

Human beings are inseparable from water on the earth, and water resources can be said to be one of the important natural resources for the survival of most organisms on the earth. So where does the water on Earth come from? Let's find out.

01 The solar system was formed 4.6 billion years ago in a nebula, and the gas and dust in the nebula were left over from many supernovae** from much earlier.

02 Hydrogen is the most abundant element in the universe, and at the end of stellar evolution, hydrogen gradually coalesces into heavy elements, and small stars eventually fuse into carbon, oxygen, silicon, and other elements.

03 After the supernova eruption, the primordial nebula of the solar system was formed, which contained a large amount of hydrogen, helium, nitrogen, oxygen, aluminum, silicon, iron, calcium and other elements, of which hydrogen and oxygen were relatively abundant.

04 The primordial nebulae are gravitationally concentrated, in which oxygen and hydrogen have a large chance to combine to form water, which has been preserved since the formation of the earth to the present.

05 A large number of meteorites fall into the Earth's atmosphere every day, and in the history of the Earth's existence, a large number of asteroids carrying water molecules have fallen into the Earth, which have become part of the Earth's water resources.

The earth itself: like other celestial bodies, the earth does not exist out of thin air, but is formed by the collision and fusion of many small stars, at the beginning the earth was only an asteroid, but there are constantly small celestial bodies that collide and merge with it, making its volume and mass larger and larger, at that time, there is actually water on the earth.

Outer space: With the development of science, people have discovered that outer space also sends water to the earth from time to time. Part of this water comes from small meteorites, and part of the mountain air comes from the solar wind.

In 1987, when scientists analyzed satellite imagery, they found that there were many dark spots on the earth's surface. Scientists believe that these dark spots are caused by small ice hockey balls hitting the atmosphere. Tens of millions of small ice balls hit the Earth's atmosphere every round of liquid day, and the water they bring will enter the Earth's atmosphere and oceans, replenishing the Earth's water supply.

Water production and **

Hydrogen atoms and oxygen atoms combine to form water, and as we all know, the earth is a planet in the solar system, and hydrogen and oxygen atoms are important components of the formation of the solar system. A large number of oxygen and hydrogen atoms collided to form water molecules, forming nebulae in the solar system, and the earth was formed by the dust and nebulae in the solar system.

The retention of water molecules, when the earth was just formed, the temperature of the earth's surface was extremely high, so that the newly formed water molecules could not exist on the earth in liquid form. Therefore, some of the water molecules formed by the initial combination of hydrogen and oxygen are combined with minerals to form aqueous crystals, and these aqueous crystals are dehydrated to obtain water. The other part of the water evaporates into water vapor and remains in the atmosphere, where it returns to the surface in the form of rainfall.
