-Extends from the earths surface (on average 12km up).
-Temperature decreases with altitude in troposphere.
-Lots of turbulence as warm air rises through the layer and then the cold air sinks.
-Lots of clouds due to there being lots of water vapour.
-Boundary between troposphere and stratosphere jet streams.
-Extends from around 12km to around 50km up.
-Temperature increases with altitude in this layer because the ozone layer is found in the lower stratosphere. UV radiation is absorbed which then warms up the upper stratosphere.
-The stratosphere isn't turbulent as there are not many clouds.
-Boundary of stratosphere and mesosphere.
-The mesosphere extends from around 50km and 85-90km up.
-Temperature decreases with altitude in the mesosphere. It is warmed up by the stratosphere. The further away from the stratosphere the cooler it gets.
-Mesopause is the boundary of the mesosphere and thermosphere.
-Extends from 85-90km to around 1000km up.
-Temperature increases with altitude in the thermosphere. This is because small amounts of oxygen in this layer absorb UV radiation, warming the thermosphere.
