Explanation:
People who use marble to carve monuments and sculptures are always concerned because it can easily chemically weather.
Marble is a metamorphic rock derieved from limestone. The minerals that makes up limestone are calcite and dolomite. When a metamorphic transformation occurs, the rock is subjected to intense temperature and pressure. Marble is made of calcite and dolomite minerals.
