Thermosphere
What is it?
The thermosphere is the layer of the earth's atmosphere that lies above the mesosphere at altitudes between 80 and 200 kilometers above the earth's surface. The thermosphere is also the lower part of the ionosphere.
Give me an example!
The lower levels of the thermosphere are composed of molecules of nitrogen (N and N2) and Oxygen (O and O2). The higher you go in the thermosphere, the warmer the temperature becomes because solar radiation is absorbed by oxygen molecules.
