What causes acid rain the burning of fossil fuels (coal and oil) by power– production companies and industries releases sulfur into the air that combines with oxygen to form sulfur dioxide (so2) exhausts from cars cause the formation of nitrogen oxides in the air from these gases, airborne sulfuric acid (h2so4) and nitric. 10 introduction note: this text refers to 19 overheads which are graphics not contained in this electronic version of the text these overheads are available in acid rain is a lay term for a widely recognized environmental affliction caused by chemical reactions in the atmosphere of emissions of polluting species such as. Acid rain occurs when sulfur dioxide and nitrogen oxides—gases released by the burning of fossil fuel—form acidic compounds in the atmosphere in later years, they began to understand how acidification can also cause imbalances in soil chemistry, exacerbating problems for watersheds and plant life.

When acid rain falls to earth, it damages plants by changing soil composition degrades water quality in rivers, lakes and streams damages crops and can cause buildings and monuments to decay like humans, animals can suffer health effects from exposure to air pollution birth defects, diseases, and. What is acid rain first identified in 1872 in sweden and studied in the us beginning in the 1950s, acid rain is precipitation in the form of rain, snow, hail, dew, or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground sulfur dioxide (so2) and nitrogen oxides (no, no2) are bi-products.
