Acid rain is a type of precipitation that has a lower pH than normal rainwater, typically between 4.2 and 4.4. It is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, which react with water, oxygen, and other substances to form sulfuric and nitric acids. These acids then fall to the ground in rain, snow, sleet, or fog. Acid rain can seriously affect the environment... When it falls to the ground, it can make the soil more acidic, which can harm or kill plants and trees. Acid rain can also acidify bodies of water, affecting the pH of the water and the species that live in it. Acid rain can also corrode buildings, statues, and other structures made of stone or metal One of the major sources of acid rain is the burning of fossil fuels, such as coal and oil, which releases large amounts of sulfur dioxide and nitrogen oxides into the air. These substances can then be carried long distances by wind and can cause acid rain to fall far from the point of origin.
