What is the height of the earth's atmosphere?

There is no exact business department. Generally speaking, it is more than 1000 km.

The atmosphere is mainly composed of nitrogen, oxygen and argon, of which nitrogen accounts for 78. 1%. It is the main component of the atmosphere, with oxygen accounting for 20.9%. Argon accounted for 0.93%. There is a small amount of carbon dioxide in the ocean, and there is little gas and water vapor. Generally speaking, there are still thin gases and basic particles at the height of 2000 to 16000 km above the surface, and there are also a small amount of gases in underground soil and some rocks. These are generally considered as a part of the atmosphere, and the air density in the atmosphere decreases with the increase of height, so the higher the air, the thinner it is.

The earth's atmosphere rises vertically from the surface and is usually divided into five layers: troposphere, stratosphere, mesosphere, thermosphere and outer atmosphere.
