Metamorphic (meta means ‘form’ and morphic means ‘change’) rocks are the transformed form of igneous or sedimentary rocks. They are formed when these rocks experience intense heat and pressure deep inside the Earth’s crust. For example: limestone (sedimentary) converts to marble (metamorphic) when it comes in contact with high heat and pressure. Metamorphic rocks are commonly found in mountainous regions because in these regions these rocks have come out on the surface during mountain formation.
