Acid rain is the state when the pH of rain falls below 5-6-xA0- Acid rain damages the buildings and statues as they dissolve and corrodes the heavy metals- This happens when sulphuric acid nitric acids in the polluted air react with calcite in marble- the calcite dissolves- It also dissolves metals from soils- rocks and sediments-xA0-xA0-
