What are the main components 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".

Methane, ammonia, water.

In fact, there are other components of the primordial atmosphere, but these three components are the most important for life and should be the correct answer.

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.

Composition of the original atmosphere: methane, ammonia, water vapor, hydrogen, etc., as well as some hydrogen sulfide and hydrogen cyanide.

The primordial atmosphere of the early days of the Earth's formation was dominated by the most abundant light matter in the universe: hydrogen, helium and carbon monoxide. Due to the solar wind (a large stream of material erupted by stars, which coincided with the early days of the formation of the sun) and the warming of the Earth, the primordial atmosphere gradually expanded into space and escaped and was lost.

It is estimated that 4.5 billion years ago or later, there was no atmosphere on Earth.

The main components are: water vapor, hydrogen, ammonia, methane, hydrogen sulfide, carbon dioxide, etc., and there is no oxygen in the original atmosphere. 4.5 billion years ago, the earth was subjected to a strong and frequent collision of meteorites 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, and these star-like objects collided with each other.

The earth is in a molten state, and a large amount of gas originally contained in the meteorite is volatilized. Due to the high nuclear transition energy in the Earth's interior, the strong impact, and the strong thermal radiation of the Earth, the surface air temperature has always been higher than the boiling point of water.

Water vapor cannot be condensed into water, at this time, carbon dioxide, nitrogen and water vapor are the main gas components, almost all of which accumulate in the atmosphere, forming the densest volcanic gas circle, and the atmospheric pressure is very large, which forms the first appearance of the earth's air.

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.

The main components of the native atmosphere include carbon monoxide, methane, hydrogen, ammonia, and water vapour.

There was no nitrogen and oxygen in the earth's primitive atmosphere, and the main components were carbon monoxide, methane, hydrogen, ammonia and water vapor.

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

The composition of the atmosphere is complex, and in addition to oxygen and nitrogen, there are gases such as hydrogen, carbon dioxide, helium, neon, argon, krypton, xenon, and ozone. Nitrogen and oxygen each account for the sum of the total volume of air, and the sum of other gases is less than 1% of the total volume of air. The atmosphere also contains a certain amount of water and various dust impurities, which are important substances for the formation of clouds, rain, fog and snow.

What are the components of the atmosphere?

The various gases that make up the air are air components. Air usually refers to a mixture of various dry gases and is the main component of the atmosphere. The composition varies depending on the level of the atmosphere. Tropospheric air accounts for the vast majority of the total and has the greatest impact on humans.

If expressed in terms of volume ratio, the content of the four main gases in the troposphere is: nitrogen, argon, and carbon dioxide are slightly higher than 3 parts per ten,000, and the total of the four gases is reached. There are very few other gases, including neon, helium, methane, hydrogen, nitrogen dioxide, carbon monoxide, ozone, etc., as well as very small amounts of carbon, nitrogen, and sulfur compounds.

The air in the atmosphere is invisible, but it is surprisingly massive. Scientists estimate that there are more than 500 billion tons of air around the entire planet. People who live on Earth will be crushed to pieces if there is no outward pressure from the human body.

Due to the gravitational pull of the Earth, nine-tenths of the atmospheric mass is concentrated in the atmosphere within 16 kilometers near the surface. The higher above the ground, the thinner the air.
