The atmosphere is mainly composed of Nitrogen and Oxygen.
The atmosphere is divided into different layers:
The thickness of the atmosphere varies from 7km at the poles to 20km at the equator. At our latitudes, it is about 11km.
A standard atmosphere is defined, assuming a pressure of 1013.25 hPa at sea level, and a Standard Temperature of 15°C.
