What is the main physical reason aircraft flight is relatively smoother in the stratosphere?
Answer and explanation
Correct answer: Low convection and fewer weather disturbances
The stratosphere has relatively stable, layered air because temperature generally increases with height, which suppresses strong vertical convection. It is also much drier and contains fewer clouds and storms than the troposphere. Therefore aircraft can experience fewer weather-related disturbances there, so option A is correct. Pressure is not higher than at the surface, and the region is not a vacuum.
