Atmospheric Structure
The atmosphere can be broken down into different layers (strata) based on its temperature and composition:
Strata based on Temperature:
Troposphere
Located 0-12km above the earth's surface, the troposphere is the lowermost layer of the atmosphere.
Stratosphere
Mesosphere
Thermosphere
Strata based on Composition:
Homosphere
Heterosphere
