Question

(d) In which layer of the atmosphere do airplanes fly?​

Answer 1

Answer:

stratosphere

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
