In which layer does air pressure decrease rapidly with height near the surface?
Answer and explanation
Correct answer: Troposphere
The governing concept is the relationship between atmospheric pressure and altitude. Near Earth’s surface, the troposphere contains the greatest concentration of air because the weight of overlying air is largest there. As height increases through this lowest layer, pressure falls rapidly. Hence option A is correct. The exosphere, mesosphere and thermosphere are much higher regions with already very thin air, so they are not the intended near-surface layer.
