Solution
The most stable and calm layer of the atmosphere is the stratosphere.
Explanation:
The stratosphere lies above the troposphere and extends up to about 50 km. It is considered stable and calm because it lacks clouds and weather phenomena found in the troposphere. Temperature in this layer increases slowly with height due to absorption of ultraviolet radiation by the ozone layer, making it relatively stable and ideal for flying jet planes. There are no turbulent weather changes in the stratosphere, unlike in the troposphere, hence it is called the most stable layer of the atmosphere.
