Why do ordinary clouds rarely form in the stratosphere?
Answer and explanation
Correct answer: Water vapour is low and air is stable there
The governing concept is that cloud formation generally needs sufficient moisture and rising, cooling air. The stratosphere contains little water vapour and has stable, layered air, so vertical uplift is weak and ordinary clouds rarely develop. Therefore option A is correct. Ocean water cannot reach the layer, pressure decreases rather than being highest, and daily snowfall is not a general feature there.
