In which layer of the ozone layer do the various weather changes occur?

The atmosphere is also called the atmosphere, and the earth is surrounded by this thick atmosphere. The main components of the atmosphere are nitrogen, which accounts for 78 1; Oxygen accounts for 20 9 ; Hydrogen accounts for 0 93; There are also small amounts of carbon dioxide, helium, neon, krypton, xenon, and water vapor. The density of air in the atmosphere decreases with altitude, and the higher the air, the thinner it becomes.

The thickness of the atmosphere is about 1,000 kilometers or more, but there are no clear boundaries. The entire atmosphere exhibits different characteristics with different altitudes, and is divided into troposphere, stratosphere, mesosphere, warm layer and fugitive layer, and above it is interstellar space.

The troposphere is the lowest layer of the atmosphere, close to the Earth's surface, and is about 10 to 20 kilometers thick. The atmosphere of the troposphere is greatly affected by the earth, and phenomena such as clouds, fog, and rain all occur in this layer, and water vapor is almost all present in this layer. The temperature in this level decreases with altitude, and for every 1000 meters of elevation, the temperature decreases by 5 6 meters.

The survival of animals and plants, and most of the activities of human beings, are also in this layer. Because the air convection in this layer is obvious, it is called the troposphere. Above the troposphere is the stratosphere, about 20 to 50 kilometers above the Earth's surface.

The air in the stratosphere is relatively stable, and the atmosphere flows smoothly, so it is called the stratosphere. There is very little water vapor and dust in the stratosphere, and below 30 km in the stratosphere, the temperature is around 55. Above the stratosphere is the mesosphere, about 50 to 85 km above the Earth's surface, where the air is already very thin, characterized by a rapid decrease in temperature and a strong vertical convection.

Above the mesosphere is the warm layer, which is about 100 to 800 kilometers above the Earth's surface. The most prominent feature of the warm layer is that when the sunlight shines, the ultraviolet rays in the sunlight are absorbed by a large amount of oxygen atoms in the layer, so the temperature rises, so it is called the warm layer. The fugitive layer is above the warm layer and is made up of charged particles.

In addition to this, there are two special layers, namely the ozone layer and the ionosphere. The ozone layer is 20 to 30 kilometres above the ground, effectively between the troposphere and stratosphere. This layer is mainly caused by the actinization of oxygen molecules by the ultraviolet rays of sunlight, which turns the oxygen molecules into ozone.

The ionosphere is thick, about 80 kilometers above the Earth's surface. The ionosphere is a gas in the high air, irradiated by the ultraviolet rays of sunlight, ionized into charged positive and negative ions and some free electrons. The ionosphere has a great influence on electromagnetic waves, and we can take advantage of the characteristics of electromagnetic short waves reflected back to the ground by the ionosphere to achieve long-distance communication of electromagnetic waves.

Under the gravitational pull of the earth, a large amount of gas gathers around the earth, forming an atmosphere of thousands of kilometers. The density of the gas becomes thinner and thinner as the height above the ground increases. Sounding rockets still found a rarefied atmosphere at an altitude of 3,000 kilometres, and it is suggested that the upper limit of the atmosphere may extend to about 6,400 kilometres above the ground.

Scientists estimate that the mass of the atmosphere is about 6,000 trillion tons, almost one millionth of the total mass of the earth, including 78% nitrogen, 21% oxygen, argon, carbon dioxide neon, water vapor and dust.

Various weather changes occur in the troposphere of the atmosphere, and above the troposphere is the stratosphere. The ozone layer is at the bottom of the stratosphere near the troposphere.

The ozone layer is mainly distributed in the stratosphere.

The Earth's atmosphere can be divided into three parts: the troposphere, the stratosphere, and the upper atmosphere. The stratosphere is dominated by advection, the stratosphere is suitable for aviation flight, the content of water vapor and impurities in the atmosphere is very small, there is no cloud and rain phenomenon, the visibility is high, and it is suitable for the flight of the spike.

The ozone layer in nature is mainly distributed in the stratosphere, about 20 to 30 kilometers above the ground, the ozone in this layer absorbs a large amount of solar ultraviolet rays, warming the atmosphere, the ozone layer has the effect of protecting life on the earth, known as the "umbrella of life on the earth". The ozone layer is the umbrella of the earth, and ozone absorbs high-intensity ultraviolet rays, shielding us from excessive exposure to ultraviolet rays.

The ozone layer is the stratosphere of the atmosphere at which ozone concentrations are high. The ozone in the ozone layer is mainly produced by ultraviolet light. The functions are: 1. Protective.

The ozone layer absorbs ultraviolet rays below the wavelength of sunlight, protecting people, animals and plants on Earth from short-wave ultraviolet light.

2. Heating effect.

Ozone absorbs ultraviolet rays from sunlight and converts them into heat energy to heat the atmosphere.

3. The role of greenhouse gases. The role of ozone is also very important in the upper troposphere and at the bottom of the stratosphere, at very low temperatures.

The ozone layer is composed of ultraviolet light, oxygen molecules, oxygen atoms, carbon atoms, carbon dioxide and other gases that react with each other. The role of the ozone layer is to protect the earth, heat the ultraviolet rays, convert the ultraviolet rays into heat, reduce the temperature of the earth, and keep the earth in a greenhouse environment.

It is composed of the atmosphere, ozone content, or nitrogen and oxygen atoms in it, which can play a protective role, can also play a role in heating, can also ensure the greenhouse gas, can absorb sunlight, but also can avoid ultraviolet damage.

Its main component is the material in the stratosphere of the atmosphere. The role of the Earth's ozone layer is to prevent large amounts of ultraviolet rays from being ingested to the ground.

Ozone depletion is not directly related to the greenhouse effect, but indirectly, and the greenhouse effect is mainly caused by greenhouse gases, such as carbon dioxide and methane. When they are in the sun, the sun can penetrate and shine in, and they also absorb heat. When the sun can't reach them, they release heat and stop the Earth's heat from escaping into space, causing the average temperature of the Earth to rise.

<> ozone is mainly destroyed by the use of R12 refrigerant in the past and now, and the damage is extremely serious, and most of the R22 refrigerant will be used in the future, and the damage is relatively small (about 10% of the previous bending rate) but the overall damage is still very serious. At present, there are only some high-end air conditioners and refrigerators, etc., the use of refrigerants such as R134 does not harm the ozone In fact, the refrigerant R134 is more expensive than the former, and the requirements for the compressor will be relatively high, manufacturers are unwilling to invest, and now there are agreements everywhere in the world, all require new units to use R134 and other environmentally friendly refrigerants, and many countries also have legal provisions.

Why is the ozone hole only found in the polar regions? The main reason is that the temperature in the polar regions is very low. The polar vortex gradually rises into the stratosphere, accelerating the depletion of the ozone layer, which can easily be broken through with the help of Freon.

Cold vortices are more difficult to form than in warmer parts of the planet, and higher temperatures also protect the ozone layer. While temperature is critical to the ozone layer, limiting human use of CFCs does play an important role. Sadly, global warming may be protecting the Earth's ozone layer.

On the other hand, a global phenomenon that threatens to destroy humanity may be covertly protecting it.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, the like is the biggest help to me, thank you.

This statement is not quite accurate, because it is not objective. Although rapid global climate change has caused many environmental problems, the ozone layer hole exists in the first place, so it is not directly caused by global climate change.

This is not entirely true, and some of it is indeed due to industrialization, and of course it is also directly related to global warming.

This is only part of the reason, but there is also more and more carbon dioxide in the air, which is why this phenomenon can occur.

This statement is not entirely true, except that HCFCs in chemical agents are the main cause of ozone reduction.

The ozone layer is the stratosphere of the atmosphere at which ozone concentrations are high.

Ozone layer action.

1. One is the protective effect, the ozone layer can absorb ultraviolet rays below the wavelength in sunlight, mainly a part of UV-B (wavelength 290 300nm) and all UV-C (wavelength<290nm=, to protect humans, animals and plants on the earth from short-wave ultraviolet rays.

2. The second is heating, ozone absorbs ultraviolet rays in sunlight and converts it into heat energy to heat the atmosphere, due to this effect, the atmospheric temperature structure has a peak at an altitude of about 50km, and there is a warming layer 15 50km above the earth.

3. The third is the role of greenhouse gases, in the upper troposphere and the bottom of the stratosphere, that is, at the height of very low temperatures, the role of ozone is also very important. If ozone decreases at this height, there will be a drive to lower the surface air temperature. Therefore, the high distribution and variation of ozone is extremely important.
