B) temperature
C) stability
D) depth
E) visibility

Question

Quizplus · Accepted Answer

The stability of the air layer, which refers to its tendency to either mix or stratify, plays a key role in determining the dispersion of pollutant material in the atmosphere. Unstable air leads to greater mixing and dispersion, while stable air can trap pollutants close to the surface, leading to higher concentrations. The other factors listed may also affect dispersion to some extent, but stability is the most important determinant.
