Acid rain marble cancer.
Statues and structures are made up of marble limestone etc are slowly corroded as acidic.
Causes of marble cancer.

Various gases like sulphur dioxide oxides of nitrogen are released from factories.
Please watch the video below where scientists and archaeologists describe the cause of taj mahal changing its color.
Also when it rains the oxides of sulfur and nitrogen present in air react with it to form.
Presence of calcium carbonate in the acid rain.
In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
Statues and structures made up of marble and limestone are slowly corroded as the rain water containing the acids fall on them both sulphuric acid and nitric acid dissolve marble to form salts acid rain corrodes the marble of the monument this phenomenon is also known as marble cancer.
When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
Acid rain corroded the marble of the monument.
Acid rain rain is called acid rain only if it has more acid than normal.
This phenomenon is called as marble cancer.
The rainwater falls on them.
