A weather balloon rises steadily and a sensor records temperature falling, then beginning to rise again. The point where temperature stops falling and starts rising marks the boundary between the:
In the troposphere temperature falls with height, but in the stratosphere it rises again due to ozone absorbing UV rays, so the turning point is the tropopause between them.
Assertion (A): Temperature rises with height in the stratosphere but falls with height in the troposphere. Reason (R): The stratosphere is heated mainly by ozone absorbing ultraviolet radiation, while the troposphere is heated mostly from the Earth's surface below. Choose the correct option.
Surface heating warms the lower troposphere so it cools upward, while ozone absorbing UV warms the stratosphere upward; R correctly explains the opposite temperature trends in A.
