What effect can stratospheric stability have on air pollutants?
Answer and explanation
Correct answer: Pollutants can persist for a long time
The governing concept is stable stratification and weak vertical mixing. In the relatively stable stratosphere, vertical motion is suppressed, and the scarcity of ordinary rain limits wet removal. Consequently, pollutants or aerosols introduced there may remain and spread for a long time. Option B is correct. Immediate rain washout is not typical, and the other choices describe physically irrelevant movements or transformations.
