Question

what role does wind play during a temperature inversion? it has no effect on pollution levels. it helps to disperse air pollutants. it creates temperature inversions. it exacerbates buildup of pollutant.

Explanation:

During a temperature inversion, air is stable with a layer of warm air over cooler air. Wind can disrupt this stable layer. If there is wind, it can mix the air, which helps in dispersing air pollutants. Temperature inversions are mainly caused by factors like radiation cooling (not wind). And wind does not exacerbate pollutant buildup (rather lack of wind might). Also, wind has an effect on pollution levels (so the first option is wrong).

Answer:

It helps to disperse air pollutants.
