Your question: How does acid rain affect gravestones?

Does acid rain Affect stone?

Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfurous, sulfuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves. … Eventually the black crusts blister and spall off, revealing crumbling stone.

What impact does acid rain have on gravestones and historical buildings?

Old statues, monuments and tombstones are vulnerable to acid rain because they were made of limestone. Over decades of exposure to acid rain, the details of a statue can be lost, slowly turning them into featureless blobs. Acid rain has also attacked the chiseled words on some tombstones, rendering them unreadable.
