Question

Quizplus · Accepted Answer

Chemical cycles such as photochemical reactions and precipitation (rain, snow) can remove some air pollutants from the atmosphere. Gravity also plays a role in removing pollutants through sedimentation and dry deposition. However, large amounts of pollutants can overwhelm these natural processes and lead to harmful levels of pollution.
