Detailed explanation-1: -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.

Detailed explanation-2: -Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Detailed explanation-3: -Acid rain is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, where they react with water, oxygen, and other chemicals to become sulfuric and nitric acid respectively. The pH of acid-impacted rain is generally below 4.5 on the pH scale.

Detailed explanation-4: -Acid rain is one of the consequences of air pollution. Gases produced from the burning of fuels react with the oxygen in the air and water vapour, transforming into acids that fall onto the earth’s surface as rain.

Detailed explanation-5: -Causes of acid rain The biggest sources are coal-burning power plants, factories, and automobiles. When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere.
