when acid rain is formed?
Answers
Explanation:
Acid rain is one of the consequences of air pollution. It occurs when emissions from factories, cars or heating boilers contact with the water in the atmosphere. These emissions contain nitrogen oxides, sulfur dioxide and sulfur trioxide, which when mixed with water become sulfurous acid, nitric acid and sulfuric acid. This process also occurs naturally through volcanic eruptions.
I hope it's helpful!!
Explanation:
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.
While a small portion of the SO2 and NOX that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels. The major sources of SO2 and NOX in the atmosphere are:
Burning of fossil fuels to generate electricity. Two thirds of SO2 and one fourth of NOX in the atmosphere come from electric power generators.Vehicles and heavy equipment.Manufacturing, oil refineries and other industries.
Winds can blow SO2 and NOX over long distances and across borders making acid rain a problem for everyone and not just those who live close to these sources.
Wet deposition is what we most commonly think of as acid rain. The sulfuric and nitric acids formed in the atmosphere fall to the ground mixed with rain, snow, fog, or hail.
A better example for this acid rain is Taj Mahal
now because of pollution these acid rains are destroying Taj Mahal's marbles .Effects of acid rain on Taj Mahal
Taj Mahal is completely made of marble, acid rains reacts with marble to form a powder-like substance which is then washed away by the rain. This phenomenon is called marble cancer. ... Sulphur and nitrogen oxide are the main pollutants which react with air to formEffects of acid rain on Taj Mahal
