What is the difference between the current atmospheric composition and the original atmospheric comp

The main components of the primordial atmosphere are:Methane, ammonia,Hydrogen sulfide, water vapor, etc., the composition of the atmosphere is probably 78 nitrogen and 21 oxygenCarbon dioxide0 03, other information is unknown, basically it should be these three. Geologists believe that the Earth was formed about 4.6 billion years ago, and that the temperature on the primitive Earth was high and there was no life on the Earth. The sky is either a full day of scorching sun, or a whole day of thunder and lightning, volcanic eruptions.

It often occurs on the ground.

The water vapor from the volcanic eruption, hydrogen, ammonia, methane and other gases are released in large quantities and accumulate in the air, which eventually forms the initial atmosphere, which is worth noting to all of us that there was no oxygen in the primordial atmosphere, because although a small amount of water vapor was subjected to strong ultraviolet rays.

and decomposes into hydrogen and oxygen, however, hydrogen floats to the top of the atmosphere because it is too light, and most of it gradually disappears into space, while oxygen quickly combines with some matter on the ground to form oxides.

Therefore, in the primordial atmosphere there is no oxygen, so the environment in the primordial atmosphere is very harsh, because there is no oxygen, it is not suitable for living organisms at all, when Laplace.

At that time, he mentioned that the nebula may have begun to condense and a large amount of gas was already surrounding the Earth. The main components of the primordial atmosphere were hydrogen and helium, radioactive materials in the Earth's interior when the Earth was formed.

The decay will lead to the conversion of energy. This conversion has implications for the maintenance and extinction of the Earth's atmosphere.

In addition, the solar wind.

The powerful action and the small gravity of the earth when it was just formed caused the primitive atmosphere to disappear rapidly, and after the creation of the earth in the secondary atmosphere stage, condensation occurred on the earth's surface due to the decrease in temperature, and the high temperature in the earth's interior promoted the frequent activity of volcanoes because of volcanic eruptions.

when he will form volatile.

Gases gradually replaced the original atmosphere and became a sub-atmosphere.

On the question of what is the difference between the current atmospheric composition and the original atmospheric composition, it will be explained here today.

The main components of the primordial atmosphere were methane, ammonia, hydrogen sulfide, water vapor, etc. The current atmospheric composition is about 78 percent of nitrogen, 21 percent of oxygen and 21 percent of carbon dioxide. Other information is unknown, basically all of them should be these three.

Geologists believe that the Earth was formed about 4.6 billion years ago. The temperature on the primordial Earth was high, and there was no life force on the Earth. The sky is either a full day of scorching sun or a full day of thunder and lightning, and volcanic eruptions often occur on the ground.

The main components of the original large leakage gas are: water vapor, hydrogen, ammonia, methane, hydrogen sulfide, carbon dioxide, etc., and there is no oxygen in the original atmosphere.

The formation of the primordial atmosphere4.5 billion years ago, the earth was subjected to a strong and frequent collision by a frozen planet, meteorites collided at high speed, and their kinetic energy was converted into internal energy, generating a large amount of heat, making the earth's surface reach 1,500 degrees Celsius.

Due to the high nuclear transformation energy inside the earth, the impact is strong, the earth's thermal radiation is strong, the surface air temperature is higher than the boiling point of water, and the water vapor cannot be condensed into water.

The original atmospheric components include ammonia (NH3), methane (CH4), and steaming bridge gas (H2O).

1. Ammonia (NH3).

Ammonia is thought to be one of the important components in the original atmosphere. Research has shown that there was an abundance of ammonia gas on the primitive Earth, which was produced by the reaction of hydrogen and nitrogen in the early days. Ammonia has a strong odor and is toxic, but it plays an important role in some chemical reactions and life.

2. Methane (CH4).

Methane is also a possible component in the pristine atmosphere. It is produced by active biological or chemical processes in the subsurface or on the surface. Methane is able to be released into the atmosphere during the metabolism of some fungi, bacteria, and ancient microorganisms.

Methane played an important role as a greenhouse gas in the primordial atmosphere, maintaining the Earth's early temperature equilibrium.

3. Water vapor (H2O).

Water vapor is one of the most important components of the Earth's primordial atmosphere. Early underground volcanic eruptions and the cooling of magma triggered the release of large amounts of water vapor into the atmosphere, while the Earth's high temperature and lack of liquid water bodies led to extremely high humidity in the atmosphere. Water vapor is one of the earth's greenhouse gases and helps keep the planet warm.

The difference between the composition of the primitive atmosphere and the modern atmosphere:

1. The fossil record.

Through the analysis of fossils and rocks preserved on Earth, scientists can deduce the composition of the original atmosphere. For example, by studying the stomata and leaf morphology in ancient plant and animal fossils, it is possible to infer the level of carbon dioxide in the atmosphere at that time. In addition, by analyzing the fossil ferns in rocks and carbon isotopes in the remains of marine organisms.

2. Astronomical research.

Through the study of other planets and small bodies in the solar system, the composition of the primordial atmosphere can be indirectly understood. For example, the analysis of the atmospheres of planets such as Mars and Venus can be compared with the original Earth's atmosphere, exploring the differences and similarities between them. In addition, the study of comets and meteorites has provided important clues about the origin of the solar system and the composition of the original atmosphere.

3. Numerical simulation.

Using computer models and numerical simulations, scientists can reconstruct and simulate the atmospheric environment in the early days of the Earth's formation and its possible components. These models take into account factors such as the initial conditions of the skura holding the ball, solar radiation, crustal activity, biological interactions, and other factors to estimate the amount of various gases in the primordial atmosphere.

Scientists speculate that the atmosphere of the primitive Earth was also such a strongly reducing atmosphere, based on the fact that the gas ejected from the volcanic eruption, as well as Jupiter and Saturn, which are far away from the Sun and have less change, and whose atmospheres are now composed mainly of methane, ammonia, and hydrogen.

They believe that the original Earth's atmosphere had no oxygen in its composition, but reducing gases such as hydrogen, carbon dioxide, ammonia, methane, hydrogen sulfide, and hydrogen cyanide. However, since the 80s of the 20th century, some scholars have doubted this. They believe that there were no ammonia, methane, and hydrogen sulfide gases in the primitive atmosphere, because these gases are easily decomposed by ultraviolet radiation, and most of the hydrogen released will escape into the air, so the main components of the early primitive atmosphere are water vapor, carbon monoxide, carbon dioxide, nitrogen, and possibly some free hydrogen.

If, given that there was no ammonia and methane in the primordial atmosphere, or only in very small amounts, it was impossible for the primordial atmosphere of the earth to produce organic matter and amino acids under the action of various natural conditions, then Miller's experiment is doubtful. Therefore, this view provides indirect support for the "Usheng theory".

Atmospheric composition refers to the various gases and particles that make up the atmosphere. Including clean air, water vapor, dust.

The earth's atmosphere has constant gas components such as nitrogen, oxygen, and argon, gas components such as carbon dioxide, rock monoxide, lead, and nitrogen, which are relatively fixed, and there are also gases such as water vapor, carbon monoxide, sulfur dioxide, and ozone, which are very variable. Solid and liquid aerosol particles such as dust, smoke particles, salt particles, water droplets, ice crystals, pollen, spores, and bacteria are often suspended.

Thermal energy**. The change of the movement of the atmosphere is caused by the exchange of heat energy in the atmosphere, which is mainly related to the sun, and the exchange of heat energy makes the temperature of the atmosphere rise and fall. The movement of the air and the change of the barometric pressure system make the energy and matter between the sea and the land, between the north and the south, and between the ground and the high altitude on the earth, resulting in complex meteorological changes and climate change.

Atmospheric science will study the causes of climate, the state of climate failure in different regions, climate change, and the impact of human activities on climate.

The atmosphere is made up of a variety of gases and also contains small amounts of solid and liquid impurities.

The whole mixture of gases in the atmosphere except for water vapor and solid impurities is called clean atmosphere. The main components of the clean atmosphere are oxygen, nitrogen, argon, and carbon dioxide sources, as well as neon, helium, ozone and other trace gases.

In terms of volume, nitrogen, oxygen, argon, carbon dioxide in the clean atmosphere, and other gases combined are less than enough. Below 90 km, the ratio of clean air composition remains roughly unchanged. Above 90 kilometers, the atmosphere is mainly composed of nitrogen and oxygen, but due to the hidden external irradiation of the sun's purple socks, oxygen and nitrogen have been ionized into charged particles.

Oxygen in the atmosphere is necessary for all life. Nitrogen can dilute the concentration of oxygen, so that the oxidation is not too violent. The amount of ozone in the atmosphere is small, but it plays an important role.

It can absorb the sun's ultraviolet radiation, affect the vertical distribution of atmospheric humidity, and also protect life on the ground from the killing effect of ultraviolet rays.

Carbon dioxide absorbs very little solar shortwave radiation, mainly absorbing long-wave radiation from the ground, while emitting long-wave radiation to the surrounding air and the ground. It can hinder the drop in surface air temperatures, the so-called "greenhouse effect".

There is also water vapor in the atmosphere. Water vapor is mainly concentrated in the near-surface layer, although the content is not much, but it plays an important role in weather changes and is the raw material for the formation of clouds and rain.

At a certain temperature, there is a maximum amount of water vapor that can be held by a certain amount of air. The air that contains the maximum amount of water vapor is called saturated moist air. This limit varies with temperature.

The lower the temperature, the smaller the maximum amount of water vapor that can be accommodated. The physical quantity that indicates the amount of water vapor in the air is the humidity of the air.

There are also various solid impurities in the atmosphere. Solid impurities are at the heart of water vapor condensation. With this core, water droplets in the atmosphere collide with each other and expand as they move up and down before they finally condense into clouds.
