Question

Quizplus · Accepted Answer

Acid precipitation, also known as acid rain, is formed due to emissions of sulfur dioxide and nitrogen oxides, which are byproducts of anthropogenic activities such as burning of fossil fuels and industrial processes. These emissions enter the atmosphere and combine with other components to form sulfuric acid and nitric acid, which then fall to the earth as acid precipitation. Therefore, acid precipitation results from human modifications of the nitrogen and sulfur cycles.
