If a layer has little water vapour but important ozone chemistry, which layer is it?
Answer and explanation
Correct answer: Stratosphere
The governing atmospheric-layer concept is that the stratosphere is dry compared with the troposphere and contains the major ozone layer. Ozone absorbs ultraviolet radiation, producing important photochemical reactions and contributing to the stratosphere’s temperature increase with altitude. Option A is therefore correct. The troposphere contains most water vapour and weather, while the exosphere is extremely rarefied and is not the principal region of ozone chemistry.
