Question

what determines whether pollutants get blown away or trapped locally? weight atmospheric stability

Explanation:

To determine if pollutants are blown away or trapped locally, we analyze the options. Weight of pollutants alone doesn't determine their dispersion; lighter pollutants can still be trapped in stable atmospheres. Atmospheric stability (the state of the atmosphere's ability to mix or restrict vertical motion) is key: in unstable atmospheres, pollutants mix and disperse, while in stable atmospheres, they get trapped near the surface. So atmospheric stability is the factor.

Answer:

B. Atmospheric stability (assuming the options are labeled, with "Weight" as A and "Atmospheric stability" as B)
