Detailed explanation-1: -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-2: -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.

Detailed explanation-3: -Oxides of Nitrogen and Sulphur form acids when reacted with water vapour present in atmosphere. Nitrogen dioxide forms Nitric acid whereas Sulphur dioxide forms sulphuric acid on reaction with water vapour. This results in acid rain. This acid damages building and plants.

Detailed explanation-4: -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. Those air pollutants react with water, oxygen, and other substances to form airborne sulfuric and nitric acid.

Detailed explanation-5: -The acids commonly present in acid rain are nitric acid, sulphuric acid and carbonic acid.
