Marble is a soft, fine- to medium-grained, metamorphic rock. It forms when limestone is exposed to intense heat, causing the minerals to melt and then crystallize. Veins and blotchy patterns often form in marble from impurities in the limestone. The intense temperatures destroy any fossils present in the original rock. Marble is used as a building and monument material. It dissolves in acid, making it vulnerable to pollution and acid rain.
