Acid Deposition
Although we associate the acid threat with rainy days, acid deposition occurs all the time, even on sunny days. Acid Deposition is the scientific term used to describe "Acid Rain ... This form of acid deposition is known as wet deposition. A second method of acid deposition is known as dry deposition. Whilst wet deposition involves the precipitation of acids, dry deposition occurs when the acids are ...
