Key concepts
3 concepts
- 1
The atmosphere is a unique reservoir that forms a protective boundary between outer space and the biosphere, where all life exists on Earth's surface.
- 2
The four layers of the atmosphere, based on temperature structure, are the troposphere, stratosphere, mesosphere, and thermosphere.
- 3
The atmosphere maintains an energy balance through radiation, convection, and conduction, with greenhouse gases trapping longwave terrestrial radiation to keep Earth warm.
