Stratosphere

Back

The layer of the atmosphere above the troposphere, characterized by an increase in temperature with increasing altitude.

Front

Mesosphere

Back

The layer of the atmosphere above the stratosphere, where temperature decreases with increasing altitude.

Thermosphere

Back

The layer of the atmosphere above the mesosphere, where temperature increases due to the absorption of solar radiation.

Front

Exosphere

Back

The outermost layer of the Earth's atmosphere, where the density is so low that individual atoms and molecules can escape into space.
