What is metamorphic rock?
Quick Answer
A metamorphic rock is a rock that has been changed by heat, pressure or chemically active fluids without fully melting. Examples include marble, slate and gneiss.
The Full Story
Metamorphism alters existing rocks deep within Earth or during mountain building, where pressure and temperature rise. Minerals recrystallize and new textures or bands can form, producing rocks like schist and gneiss. Marble comes from limestone, while slate forms from shale. The process shows that rocks can be transformed multiple times in the rock cycle.
