In which layer is vertical exchange highly limited due to atmospheric stability?
Answer and explanation
Correct answer: Stratosphere
Vertical exchange depends on convection and turbulence. In the stratosphere, temperature generally increases with altitude, producing stable stratification that resists buoyant vertical motion. As a result, air and pollutants mix much less vertically than in the turbulent troposphere. Option B is therefore correct. The lower boundary layer and monsoon troposphere usually experience stronger mixing because of heating and convection.
