What is the height of the atmosphere? What is the height of the atmosphere?

1, there is no exact business circle, 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%, which is the main component of the atmosphere, oxygen accounts for 20.9%, argon accounts for 0.93%, and there are a small amount of carbon dioxide, rare gases and water vapor in the ocean.

2. Generally speaking, at the height of 2000~ 16000 km above the surface, there are still thin gases and basic particles, and there are also a small amount of gases in underground soil and some rocks, which are generally considered to be part of the atmosphere. The air density in the atmosphere decreases with the increase of altitude, so the higher the altitude, the thinner the air will be.

3. The whole atmosphere has different characteristics at different heights, so the atmosphere is generally divided into troposphere, stratosphere, ozone layer, mesosphere, thermosphere and mesosphere. The troposphere is located at the bottom of the atmosphere, with an average thickness of about 12 km, and the thickness varies from place to place. The stratosphere is generally located in the atmosphere about 10 ~ 50 km from the surface.

4. The mesosphere, also known as the mesosphere, is located in the atmosphere between the stratosphere top and 85 kilometers. The atmosphere over 60 kilometers of the whole earth is in a state of partial ionization or complete ionization. Some people call the whole ionized atmosphere the ionosphere. Finally, the outer layer, also known as the escape layer, extends from the earth's surface to 1000 km. The temperature at this level is relatively high, reaching several thousand degrees, and the atmosphere is extremely thin.
