Question

Hey mates
explain acid rain.

Answer 1

Acid rain is a widespread term used to describe all forms of acid precipitation (rain, snow, hail, fog, etc.).

Acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that has been mixed with elements and gases .

Acid rain, also called acid precipitation or acid deposition, precipitation possessing a pH of about 5.2 or below primarily produced from the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx; the combination of NO and NO2) from human activities, mostly the combustion of fossil fuels. In acid-sensitive landscapes, acid deposition can reduce the pH of surface waters and lower biodiversity. It weakens trees and increases their susceptibility to damage from other stressors, such as drought, extreme cold, and pests.

Answer 2

Gases released from industries and factories mix with the water vapour present in the atmosphere.,once after cooled., we recieve the rain as acid rain.,

Hope it helps:-)
