However, the term acid rain was not coined until two centuries later when Angus Smith published a book called 'Acid Rain' in 1872. In the 1960s, the problems associated with acid deposition became an international problem when fishermen noticed declines in fish numbers and diversity in many lakes throughout North America and Europe. Now Acid rain is commonly know nation wide. It takes place when discharge of sulphur dioxide (S02) and oxides of nitrogen (N0x) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. This mixture then forms a solution of sulphuric and nitric acid compounds. Sunlight then increases the rate of these reactions. Theses compounds then fall to the ground in either a wet form (such as rain, snow and fog or it can fall in a dry form (such as gas particles). Once the acid rain falls the runoff water adds those acids to fully acid rain making the combination more acidic then the falling rain alone. Acid rain causes acidification of rivers and lakes.
