If convection and instability both appear in a question on atmospheric layers, which layer is the primary clue?
Answer and explanation
Correct answer: Troposphere
The governing concept is convection caused by differential heating. The troposphere is heated mainly from the Earth’s surface, so air near the ground can become warmer and less dense than air above it, producing buoyant uplift, mixing, clouds, and weather. Option B is correct. The exosphere is extremely rarefied, while the mesopause and stratopause are boundaries rather than the main region of ordinary convection and weather.
