Igneous and Metamorphic Rocks: Metamorphism in Action

Marble, a metamorphic rock, is widely used in construction and even in toothpaste. It originates from limestone, a sedimentary rock formed underwater from shells and ocean life. Over time, heat and pressure transform limestone into marble, making it a denser and smoother rock. Walking on marble is essentially stepping on the altered remains of ancient sea creatures.
