Which behaviour does temperature show through the stratosphere?
Answer: D
Absorption of ultraviolet radiation by ozone heats the upper stratosphere, so the temperature rises from about 217 kelvin at the tropopause to near 270 kelvin at the stratopause. The resulting strong stability suppresses vertical motion. Note that the temperature maximum lies well above the ozone concentration maximum, because the ultraviolet is absorbed higher up where the radiation is still intense. Working one numerical case through both cases side by side fixes the distinction better than any rule of thumb.
