What causes the stratosphere to be warmer than layers just above or below it? a. solar energy absorption by the ozone layer b. chemical reactions at the base of the layer c. heat transportation into the ozone layer by convection from the troposphere d. energetic particles hitting the mesosphere to produce heat and aurora

A.solar energy absorption by the ozone layer

The stratosphere is the almost top layer of the earth atmosphere, occupying the second position. It is found above the troposphere  and below the mesosphere. It is occupied with layer of ozone which absorbs the UV radiations coming from the sun.This makes the layer warmer as compared to other layers.

the denominator has a very specific role.
