    Acid rain is considered precipitation in the form of rain‚ snow‚ or fog. It is not regular precipitation. It is precipitation that is polluted by acid. Emissions of sulfur dioxide and nitrogen oxide into the atmosphere cause this precipitation to become acidic. These emissions are released into the atmosphere by human activity‚ such as automobiles‚ industries‚ and electrical power plants that burn fossil fuels like coal and oil. When these gases are released‚ they mix with water vapor in the clouds

    Science one world essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic
