Why is the stratosphere considered more stable than the troposphere?
Answer and explanation
Correct answer: Upward temperature increase weakens convection
The stratosphere becomes warmer with increasing altitude because ozone absorbs ultraviolet radiation. This temperature inversion suppresses vertical convection and limits turbulent mixing, so the layer is relatively stable. Therefore, option A is correct. The troposphere generally cools upward, encouraging rising and sinking air, while options B, C, and D incorrectly describe the stratosphere.
