Why is normal rain not regarded as a form of acid rain?
May 13, 2012 1:29AM
It depends on the amount of pollutants in the atmosphere. There is always an amount of Carbon Dioxide (CO2) in the atmosphere, and this causes a mild form of acid rain everywhere, so all rain is somewhat acidic.
More extreme acid rain occurs from unregulated emissions from factories and power plants.
