In which layer does temperature increase with height, helping to suppress convection?
Answer and explanation
Correct answer: Stratosphere
In the stratosphere, ozone absorbs ultraviolet radiation and warms the air at higher levels. This produces a temperature inversion: air above is warmer than air below. Such a stable arrangement discourages buoyant upward movement and suppresses strong convection, so the stratosphere is comparatively layered and calm. Therefore, option B is correct. Temperature generally decreases with height in the troposphere and mesosphere, while the exosphere is not the intended standard answer for this convection question.
