What is the approximate thickness of the Earth s surface atmosphere

The Earth's atmosphere is more than 1,000 kilometers thick, but there are no clear boundaries.

The Earth's atmosphere is the formation of an atmosphere of thousands of kilometers under the gravitational pull of the earth, when a large amount of gas gathers around the earth. It is usually divided into 5 layers: the troposphere.

Stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer close to the ground, the most active layer of the atmosphere and the most closely related to humans. The thickness of the atmosphere cannot be measured exactly, about 1,000 kilometers, we live in the atmosphere, and if we are out of the atmosphere, we will be in a state of weightlessness.

The atmosphere is like our protective layer, for example, it has enough oxygen for us to breathe, and it also has a greenhouse effect on the planet.

carbon dioxide, but also ozone and some noble gases.

Stratification of the Earth's atmosphere

1. Troposphere.

The troposphere is the lowest layer of the Earth's atmosphere. Major atmospheric phenomena such as clouds, fog, rain and snow occur in this layer. Decreasing air temperature with altitude: Since the troposphere gets its heat mainly from the ground, air temperature decreases with altitude.

2. Stratosphere.

In the stratosphere, as the altitude increases, the temperature initially remains constant or rises slightly. This temperature distribution in the stratosphere is characterized by its low influence on surface temperature, especially the presence of a large amount of ozone that can directly absorb solar radiation.

Relate. 3. The middle layer.

From the top of the stratosphere to about 80 km is the middle layer. This layer is characterized by a rapid drop in air temperature with increasing altitude and a fairly strong vertical movement.

4. Warm layer. Warm layer: It is located above the top of the middle layer. In this layer, the air temperature increases rapidly with altitude. This is due to the fact that the sun's ultraviolet radiation, which is smaller in wavelength, is absorbed by atmospheric material in the layer.

5. A fugitive layer.

This is the highest layer of the atmosphere, also known as the outer layer. The air temperature in this layer changes little with altitude. Due to the high temperature, the air particles move at a high speed, and because they are far from the center of the earth, gravity.

It is smaller, so the main feature of this layer is that atmospheric particles often escape into interstellar space.

This layer is the atmosphere.

A transition zone with interstellar space.

The thickness of the atmosphere is about 1000 kilometers or more.

The atmosphere is a meteorological term, which is a layer of mixed gas that surrounds the earth due to gravity, and is the outermost gasosphere of the earth, surrounding the ocean and land, and the thickness of the atmosphere is about 1000 kilometers or more, but there is no clear boundary. 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 atmosphere, a technical term for astronomy, is closely related to gravity.

It is the most superficial layer of gas on Earth, surrounding the deep sea and land about a kilometer thick but without a significant boundary. In fact, the atmosphere is also called the atmosphere.

It is a mixture of gases that surrounds gravity, the most superficial vapor sphere on the earth, around the deep sea and land, the atmosphere has no correct limits, there are still rare vapors and microscopic particles at an altitude of 2000 to 16000 kilometers, and small amounts of vapor also appear in the underground, soil layers and rock layers, which are also part of the atmosphere.

The key to air is nitrogen, which accounts for; Oxygen skin round occupancy; argon occupancy; There are also a small amountCarbon dioxide, noble gases (helium, neon, argon, krypton, xenon, radon) and steam. Atmospheric pressureThe density decreases with height, and the more sparse the gas becomes. The atmosphere is about 1,000 kilometers thick, but there is no significant boundary.

Let's take a look at the whole atmosphere with different altitudes, which is divided into the troposphere.

The stratosphere, the ozone layer, the mesosphere, the thermosphere and the fugitive sphere, and above that lies interstellar space.

Finish. The troposphere is located in the lowest layer of the atmosphere, stretching from the Earth's surface to the tropopause, the beginning of the stratosphere. With an average thickness of about 12 kilometers, it varies in thickness, with a thickness of 8 kilometers above the Earth's poles and 17 kilometers above the equator, which is the densest layer of the atmosphere, concentrating about 75% of the atmospheric mass and more than 90% of the water vapor mass.

Its lower boundary is connected to the ground, and the height of the upper boundary varies with geographical latitude and seasons. Its altitude varies according to latitude, with an average altitude of 17 18 km in low latitudes, 10 12 km in mid-latitudes and 8 9 km in high latitudes, and is higher in summer than in winter.

Atmospheric stratosphere.

The atmosphere is about 10 50 km from the surface. Located above the troposphere and below the fugitive layer. The stratosphere is also known as the stratosphere.

It's the Earth's atmosphere.

This layer is divided into different temperature layers, with the high temperature layer at the top and the low temperature layer at the bottom.

Atmospheric mesosphere.

The middle layer is also known as the middle layer. The atmosphere from the top of the stratosphere to between 85 km.

Atmospheric ionosphere.

The ionosphere is an ionized region of the Earth's atmosphere. The entire Earth's atmosphere above 60 kilometers is in a state of partial ionization or complete ionization, the ionosphere is a partially ionized atmospheric region, and the completely ionized atmospheric region is called the magnetosphere. It is also known that the entire ionized atmosphere is called the ionosphere, so that the magnetosphere is regarded as part of the ionosphere.

It is about 10 80 km from the surface of the Earth. The fugitive layer is above the warm layer and is made up of charged particles.

Outer layers of the atmosphere.

The exosphere, also known as the exosphere, is the outer atmosphere above the thermosphere that extends up to 1,000 kilometers above the Earth's surface. The temperature here is high, reaching thousands of degrees; The atmosphere is extremely thin, with a density of 1 billionth at sea level.

This is our atmosphere, and you still have those questions.

The Earth's atmosphere is more than 1,000 kilometers thick, and the atmosphere contains oxygen, argon, carbon dioxide, nitrogen, and some trace gases.

The atmospheric layer is very thick, because there is no or purely specific dividing line, at present, according to scientific research, its thickness is 100 million meters, which includes hydrogen, nitrogen, oxygen, rare gases, argon, krypton, xenon, radon and other gases.

Very thick, probably more than 1000 km. There is oxygen, there is nitrogen, there is argon, there is carbon dioxide, there is helium.

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 then interstellar space.

The troposphere is located in the lowest part of the atmosphere, close to the Earth's surface, and is about 10 to 20 kilometers thick.

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 about 55, the temperature is basically constant, and the temperature increases slightly with altitude in 30 km to 50 km.

Above the stratosphere is the mesosphere, about 50 to 85 kilometers above the Earth's surface, where the air is already thin, characterized by a rapid decrease in air temperature with increasing altitude and 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.

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.
