Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure.Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results.cid rain does not directly affect human health. The acid in the rainwater is too dilute to have direct adverse effects. However, the particulates responsible for acid rain (sulfur dioxide and nitrogen oxides) do have an adverse effect.
Acid Rain. Acid rain is caused when acid gases rise into the sky and mix with the clouds, this causes the clouds âabsorbâ the acid gasses and when the clouds produce rain, it falls with a higher than normal level of acidity. Rain is naturally acidic, but acid gasses make it even more acidic.cid rain is a problem all over the world, when acid gases are released, they go up in the sky, and then they are carried by strong winds. Acid rain in Scandinavian countries is caused by air pollution in Britain and other countries of Europe. In the USA, winds blow the air pollution to certain areas in Canada.
