What is one reason for weak vertical air mixing in the stratosphere?
Answer and explanation
Correct answer: Temperature increases with height there and increases stability
The governing concept is atmospheric stability. In much of the stratosphere, ozone absorbs ultraviolet radiation and warms air at higher levels, so temperature increases with altitude. This arrangement suppresses buoyant overturning: air below is cooler and denser, while warmer air remains above it. Consequently, convection and vertical mixing are weak, making A correct. Storms and abundant water vapour characterize neither the stratosphere nor this mechanism.
