Why can pollutants remain for a relatively long time after reaching the stratosphere?
Answer and explanation
Correct answer: Vertical mixing and rainfall washout are very limited
The governing concept is the stable, dry structure of the stratosphere. A temperature inversion suppresses strong vertical convection, and the stratosphere has little weather or rainfall to remove suspended material through washout. Consequently, some pollutants can spread widely and persist for long periods after entering it. Option A is correct; daily heavy rain and immediate destruction are false, while density is not higher than in the troposphere.
