What is the history of water and the origin of water

When the Earth was first born, there were no rivers, no oceans, and no life, its surface was dry, and there was very little moisture in the atmosphere. So where does the vast sea, the rushing rivers, the vast lakes, the strange shapes of the 10,000-year-old ice and snow, the clear springs surging underground, and the rain, snow and clouds in the sky come from?

It turns out that the Earth is formed by the aggregation of interstellar matter diverged from the solar nebula, and its basic composition is hydrogen and nitrogen, as well as some dust. Solid dust aggregates and combines to form the Earth's inner core, surrounded by a large amount of gas. When the Earth was first formed, it had a loose structure, little mass, little gravitational pull, and a very low temperature.

Later, due to the continuous shrinkage of the earth, the radioactive materials in the inner core produced energy, causing the temperature of the earth to continue to rise, some materials slowly warmed and melted, heavier materials, such as iron and nickel, gathered in the center to form the core, and the lightest substances floated on the surface. As the temperature of the earth's surface gradually decreases, a hard crust begins to form on the surface. However, due to the high temperature in the Earth's interior, magma activity is very intense.

Volcanic eruptions are frequent, and the earth's crust is constantly changing, with mountains rising in some places and subsiding into lowlands and valleys, while emitting large amounts of gas. As the Earth's volume continues to shrink, the gravitational pull also increases, and at this time, these gases can no longer get rid of the Earth's gravitational pull, thus surrounding the Earth, forming the "primordial Earth atmosphere". The primordial atmosphere is made up of many components, and water vapor is one of them.

Where does the water vapor come from? The solid dust that made up the primitive earth is actually a large number of fragments made of aging planets**, and these fragments are mostly inorganic salts and the like, and many water molecules are stored in 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.

When the water on the earth began to form, whether it was lakes or oceans, the amount of water was not very large, and as the water vapor produced in the interior of the earth was continuously sent into the atmosphere, the amount of water on the ground also increased, and after billions of years of earth evolution, it finally formed the rivers, lakes and seas that we see now.

A Brief History of Water Conservancy in the World.

The development of water conservancy in China can be traced back to ancient times. Legend has it that in ancient times, the Gonggong clan used earth to control floods. Ancient water conservancy in Egypt, Babylon, and India dates back to four or five thousand B.C.

The water conservancy relics of the Mayan civilization and the Inca civilization in the Americas are more than two or three thousand years old. Egyptian and Babylonian hydraulic techniques later spread to Greece and Rome. After the Renaissance, it spread throughout Europe and the United States.

Archimedes in the 3rd century BC contributed to the theory of water buoyancy, and later to Leonardo da Vinci in the Renaissance to the theory of water flow. 1824 Englishman JAspudin invented cement, which led to the development of concrete structures and brought civil engineering into a new stage of development.

In the second half of the 19th century, reinforced concrete appeared, further promoting the development of light concrete buildings. In the 70s of the 19th century, hydroelectric power stations appeared. After entering the 20th century, many new science and technology have begun to be widely used in hydraulic engineering.

For example, the use of computers for engineering-aided design and economic evaluation; The system analysis method is used to optimize the scheduling of water resources and the optimal design of the project. Water-saving irrigation technologies such as sprinkler irrigation and drip irrigation are being rapidly promoted; Remote sensing, ultrasonic and other means are used to analyze and identify the hydrogeology and engineering geology of large-scale water conservancy pivot projects. In engineering construction, water conservancy projects in the 20th century have the characteristics of large-scale, comprehensive, cross-basin, and multi-objective.

The story of the origin of water is:

Gradually condensed and formed an ocean. 2. In the early stage of the formation of the earth, the radioactivity of uranium, thorium and other radioactivity in the interior.

The decay of the elements releases heat, the interior of the earth is melted, and the moisture in the rocks is separated.

3. Volcanic eruptions release large amounts of water. After the eruption of the volcano, magma.

It flows to the surface, and as the pressure decreases, the water is released. 4. The dehydration of minerals in the earth's interior decomposes part of the water, or releases carbon monoxide.

Gases such as carbon dioxide, which react with hydrogen at high temperatures to form water.

The origin of water on Earth has been an unsolved mystery, and it was previously believed that water on Earth was caused by comets that hit Earth.

Or an asteroid brings. But French scientists in the latest issue of the American journal Science.

Through their study of meteorites, they believe that the water on Earth may be derived from hydrogen released by substances such as enstatite chondrites. This shows that the earth was formed with enough basic elements to form water, that is, the earth has been relatively humid since the day it was born.

In 2015, researchers at the University of Hawaii in the United States studied mantle rocks and concluded that surface water was part of the earth when it was formed from the earth.

The origin of the word water is an ancient story, which reflects the Chinese people's cherishing and protection of water resources, and also highlights the wisdom and achievements of ancient sages.

In ancient China, water was one of the indispensable resources for people's production and life. Therefore, the use and protection of water resources have always attracted much attention. In this context, the position of the character "water" in the Chinese character system has become more and more important.

According to legend, in ancient China, there was an expert named Xu, who was a person who knew water conservancy engineering very well. It is said that Mr. Yu once dug some canals and ditches, so that the local water source was fully utilized and protected.

In order to commemorate this achievement, the Chinese character "氵" (shui3), which means the form of water flow, was placed below the name of the person "盍", forming the Chinese character "shui3" as we know it today.

Although there is no conclusive historical record of this story, it reflects the importance and protection of water resources by the ancient Chinese people, as well as the commemoration and respect for the achievements of the sages. At the same time, it also expresses the concept of harmonious coexistence and ecological civilization in Chinese culture.

In fact, the word "water" has many symbolic meanings in Chinese culture, such as it is used to describe the character of a gentleman, such as modesty, indifference, and grandeur; At the same time, it is also used to express awe and perception of the natural world, reflecting the tradition of advocating nature, respecting nature and protecting the environment in Chinese culture.

In short, water resources are one of the indispensable basic resources in human production and life, and their protection and management are extremely important issues in contemporary society. The story of the origin of the word water reminds us that we should cherish water resources, protect the water environment, and make our ecological environment more beautiful and healthy.

The pictographic features of the spring flow disappear.

In the era of the quiet creation of the word Qilun Wang, the mountain spring splashed on the stone wall was called "water"; The water formed by the mountain spring is called "stream"; The clear stream formed by the mountain stream on the ground is called a "stream"*; The flow of water formed by the confluence of many streams is called "Chuan"; The large river formed by the convergence of many rivers is called "river", and the largest river is called "river".

Many people should know that water is a pure liquid, it can't be seen or touched, but it can make people feel very comfortable. It feels cool to wash your face with water in the summer, and it feels very comfortable to take a hot bath in the winter. Therefore, water is a thing that people can't live without.

A puddle of water on the ground was exposed to the sun and turned into water vapor, which coalesced together and became a thick cloud. The clouds accumulate heavier and heavier, forming the rain we see. The constant cycle of water is what we see every day, sunny and rainy.

Where does the water on Earth come from? Is it inherent in the human mind? No. Is it produced by human practice? Neither is it. The water on earth falls from the sky.

Regarding the ** of water on the earth, scientists previously believed that the ** of water is the interior of the earth, which was naturally produced when the earth was formed. This type of theory is riddled with holes, overstretched, and difficulties, and has hardly been taken seriously these days. American scientists recently came up with a remarkable new theory:

Water on Earth comes from comets made up of ice in space.

This theory is looking outwards in the right direction, but when it comes down to ice comets, it will create a lot of problems, such as the inability to explain why the nine planets are the only ones that make the Earth a "magnet" for a large number of ice comets?

The Earth's water is indeed placed on the Earth by some force, and the atmosphere holds this water to the Earth through the atmospheric water cycle. If there was only water and no atmosphere, even if there was a large amount of water, it would have been scattered in space long ago.

It's an extremely ingenious design.

Resources.

There was a primitive nebula of H2O molecules in the initial matter before the formation of the Earth, similar to the meteorites with average water content today, which descended to the Earth after the formation of the Earth, thus giving the Earth water.

The chemical name of water is H2O! It's a combination of hydrogen and oxygen! A water molecule is made up of two hydrogen atoms combined with one oxygen atom. The formation of water on Earth: It may be formed by volcanic eruptions during the formation of the Earth, and other long-term effects of Earth's activities.

It's because you broke my heart.

There is still a great deal of disagreement about the origin of water, and there are currently about 32 forms of water.

The doctrine of dao into the world. Here are a few examples of the doctrines of Christ's in-Christ.

One theory is that there was a primitive nebula of H2O molecules in the initial matter before the formation of the Earth, similar to the meteorites with average water content today, which descended to the Earth after the formation of the Earth, thus giving the Earth water.

Another theory holds that the original elements (hydrogen and oxygen) that formed water were formed only after the formation of the earth. Hydrogen and oxygen are combined under suitable conditions. Hydroxyl group (OH) is generated.

The hydroxyl group then undergoes complex changes to form water (H2O). The Dutch astronomer Ott believes that the main ** on Earth is the upper mantle of the lithosphere of the interior of our planet. Half of the lithosphere is made up of silicon, of which silicates and water.

These rocks are dehydrated at a certain temperature and under suitable conditions, such as volcanic eruptions, thus forming the Earth's water.

American scholar John F. Kennedy and others believed that when the rock is completely mixed in melting, it contains 75% silicate and 25% water. In the early days of the Earth's formation, volcanic eruptions were frequent, which accelerated the formation of the Earth's water. The earth's water is increasing due to the high temperatures in the earth's interior.

In the study, there is data that the ocean level has risen in the last 1,000 years. However, the rapid rise of ocean levels in recent decades may be largely due to global warming.

Where does the water come from? Water is a gift from nature. Prolonged rainwater forms water.

There are some glacial rivers that also form water. The temperature of the ground on Earth is high. The heat above the temperature flew into the sky.

When these hot gases fly into the sky, the temperature in the sky is low. As soon as they are high and low, the clouds in the sky form small droplets, which are called small raindrops.

In the early days of the earth's formation, the decay of radioactive elements such as uranium and thorium in the interior emitted heat, and the interior of the earth was melted, and the water in the rocks was separated.

Volcanic eruptions release large amounts of water. After a volcanic eruption, magma flows to the surface, and as the pressure decreases, water is released.

The origin of water on Earth is widely divided in academic circles, and there are currently dozens of different theories of water formation. Some believe that in the early days of the formation of the earth, hydrogen and oxidation in the primitive atmosphere were synthesized into water, and water vapor gradually condensed and formed oceans; It is also believed that water was originally present in the nebula material that formed the Earth.

Another view is that silicates and other substances in the primitive crust reacted and precipitated water under the influence of volcanoes. There is also an opinion that comets and meteorites, which are attracted to the Earth, are the main water on the Earth**, and even the water on the Earth is constantly increasing. Water is the most abundant natural substance on the Earth's surface, covering more than 71% of the Earth's surface, and the Earth is a veritable large water ball.

The dehydration of minerals in the earth's interior decomposes some water, or releases gases such as carbon monoxide and carbon dioxide, which react with hydrogen at high temperatures to form water. In addition, hydrocarbon combustion can also produce water, and in hard igneous rocks, there are also a certain amount of crystalline water and inclusions of primitive water.

When people study the composition of chondrites, it is found that they contain a certain amount of water, generally as high as 10% or more, while carbonaceous chondrites contain more water. Chondrites are one of the most common meteorites in the solar system, accounting for about 86% of all meteorites. Chondrites are believed to be the earliest condensations of the primordial sun, and that the Earth and other planets of the solar system were formed by the condensation of these chondrites.

Pure water can conduct electricity, but it is very weak (conductivity is negligible in daily life) and is a very weak electrolyte. Water in daily life has more positive and negative ions due to the dissolution of other electrolytes, and the conductivity is enhanced.
