How these acids affect our heritage monuments such as Taj Mahal?

Answer

Sulphur and nitric oxides present in acid rain corrode the marble, limestone, sandstone. When acid rain falls on them it breaks them down into fine powdery substances which is later washed away by rain. Taj mahal that is made of marble is being corroded by acid rain as the acid rects with the marbles.
