Question

What type of rock is marble? Describe how a piece of marble is likely to change over several years. (8 points)

Answer 1

Marble is a metamorphic rock.

Marble is a metamorphic rock, that forms when limestone (another rock) reaches a certain pressure and heat. It's composed of mostly calcite, and some other minerals like pyrite, quartz, iron oxide, and granite.

Over several years, marble is supposed to wear down from acid rain/weathering.
