Acid rain is caused by - (1) SO2 and particulates (2) (2) NO2 and particulates (3) (8) CO2 and CFCs (4) (4) SO2 and NO2

1 Answer

Answer :

(4) SO2 and NO2 Explanation: Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
