Photochemical smog is most likely to develop _____________.

Question

Quizplus · Accepted Answer

Photochemical smog forms when sunlight reacts with pollutants from vehicles and industry (such as nitrogen oxides and volatile organic compounds) in the presence of heat and stagnant air. Therefore, it is most likely to develop on days with little wind and high traffic congestion, as these conditions increase the concentration of pollutants in the air and decrease their dispersion. Option B (in coastal regions) is not necessarily true, as the presence of wind and sea spray can help to disperse pollutants. Option C (in the prairies) is also unlikely, as there are generally fewer sources of pollution and less traffic in rural areas. Option D (on cool, windy days and high traffic congestion) is incorrect, as photochemical smog formation requires heat and sunlight.
