Final answer:
Primary pollutants that lead to acid deposition are sulfur dioxide (SO2) and nitrogen oxides (NOx), which are mainly produced from burning fossil fuels. These pollutants react with water and other chemicals in the air, forming sulfuric acid and nitric acid that contribute to the formation of acid rain.
Step-by-step explanation:
Primary pollutants that lead to the formation of acid deposition include sulfur dioxide (SO2) and nitrogen oxides (NOx). The main source of these primary pollutants is the burning of fossil fuels, such as coal and oil, in power plants, factories, and motor vehicles.
These pollutants are released into the air and can react with water, oxygen, and other chemicals to form sulfuric acid and nitric acid, which then contribute to the formation of acid rain.
