What is the effect of acid rain (nitric acid) on statues, if they are made of marble (calcium carbonate)?

Acid rain is the same as putting a chunk of the marble into a beaker with the acid. The calcium carbonate will be disolved. It won't go as fast as reagent powder but the marble will be attacked and turned into carbon dioxide and calcium nitrate. Marble statues in countries that use a lot of coal have their statues turned into calcium sulfate by the SO2 + H2O__H2SO4. H2SO4 + CaCO3---CaSO4 + CO2.

Acids react with calcium carbonate and dissolve it. Chemically, the hydrogen ions of an acidic solution react with the carbonate ions forming water and carbon dioxide.
