Quizplus · Accepted Answer

Acid rain is caused when sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. These gases react with water, oxygen, and other chemicals to form sulfuric acid, nitric acid, and other toxic substances which fall back to earth in the form of acid rain. Carbon monoxide and carbon dioxide are not directly responsible for the formation of acid rain.
