Why is the stratosphere considered relatively stable for aircraft flight?
Answer and explanation
Correct answer: Convection and vertical air movement are weak in it
The governing concept is atmospheric stability. In the stratosphere, temperature generally increases with height because ozone absorbs ultraviolet radiation. This temperature structure suppresses convection and limits strong vertical mixing, producing comparatively smooth air that is useful for high-altitude aircraft. Hence option A is correct. Cyclones and strong weather mainly occur in the troposphere; surface friction is not greatest in the stratosphere, and clouds are not all at one height.
