Question

what property of the atmosphere most determines whether pollutants get blown away or become trapped locally?

• moisture
• turbidity
• color
• stability

Explanation:

To determine the correct answer, we analyze each option:

• Moisture relates to water content and doesn't directly determine pollutant movement/trapping.
• Turbidity is about cloudiness (e.g., in air, from particles) but not the key for pollutant dispersion/trapping.
• Color of the atmosphere is irrelevant to pollutant movement.
• Atmospheric stability (how air masses move vertically/horizontally) controls if pollutants are dispersed (unstable) or trapped (stable, e.g., temperature inversions). So stability is the key property.

Answer:

D. stability
