• Answer:

  Acid rain is any form of precipitation---rain ,snow ,sleet, fog-which contains high levels of sulphuric acid and nitric acid.The two important air pollutants which produce these acids are sulphur dioxide and nitrogen oxide .These pollutants combine with the water vapour in the air and produce the above acids. The sulphur dioxide gas is emitted by power stations and automobiles whereas burning of fossil fuels contribute to both nitrogen and sulphur emissions.Volcanic eruption is also considered as one of the sources of these pollutants.Occurance of acid rain has been reported both in Canada and USA Most fish species die if acid rain mixes with lake and pond water as pH value of water comes down.Aerosol of acid rain can cause respiratory disorders in human beings. THe only way to prevent acid rain is to prevent the above pollutants from mixing with atmosphere which is a difficult job.
