How it affects the Taj Mahal: Acid Rain When these gases react with the moisture (water vapor) in the air, they form Sulphuric Acid and Nitric Acid. These acids fall to the earth as Acid Rain. The Taj Mahal is made of white marble, which is chemically Calcium Carbonate . The acid rain reacts with the marble through a process called "Marble Cancer," which corrodes the stone and turns it yellow.
