Which statement correctly describes the chemical role of the stratosphere?
Answer and explanation
Correct answer: It is important because ozone chemistry absorbs ultraviolet radiation.
The governing concept is the stratosphere’s ozone chemistry. Ozone molecules absorb a significant portion of the Sun’s harmful ultraviolet radiation, especially UV-B and UV-C, thereby reducing the radiation reaching Earth’s surface. This absorption also contributes to the stratosphere’s temperature structure. Rainfall and most weather occur in the troposphere, meteors mainly burn higher in the atmosphere, and no atmospheric layer is made entirely of hydrogen. Therefore, A is correct.
