what is acid rain? how it is caused?
Answers
Answer:
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Answer:
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
This image illustrates the pathway for acid rain in our environment:
(1) Emissions of SO2 and NOx are released into the air, where
(2) the pollutants are transformed into acid particles that may be transported long distances.
(3) These acid particles then fall to the earth as wet and dry deposition (dust, rain, snow, etc.)
(4) may cause harmful effects on soil, forests, streams, and lakes.
