Eroded statue. Statue eroded by acid rain. The surface of the statue is badly pitted. Acid rain occurs when pollutants in the air, such as oxides of nitrogen and sulphur, dissolve in atmospheric water. The acids formed attack carbonate-bearing rocks such as limestone and sandstone. The acid may either fall as acid rain or form spontaneously on damp surfaces in a badly polluted area.
