Why do aircraft often prefer flying in the lower stratosphere?
Answer and explanation
Correct answer: Because weather turbulence is comparatively less there
The lower stratosphere is comparatively stable because temperature generally increases with height there, reducing strong vertical convection. With fewer clouds and storms than in the troposphere, aircraft can often experience smoother flight and less turbulence. Heavy continuous rain and maximum dust storms are not features of this layer, and oxygen is not present at sea-level concentration. Thus, option A is correct.
