If an instrument records a temperature increase in the stratosphere, what is the main chemical clue?
Answer and explanation
Correct answer: Ultraviolet absorption by ozone
The stratosphere contains the ozone layer, and ozone absorbs incoming ultraviolet radiation. That absorption converts radiant energy into heat and produces the characteristic increase of temperature with altitude in much of the stratosphere. Hence option B is correct. Water-vapour condensation is mainly a lower-atmosphere process, hydrogen does not rain in this way, and sea-salt evaporation is not the chemical cause of stratospheric warming.
