What are known as metamorphic rocks?

उत्तर
Metamorphic rocks are formed by the complete change of texture of rocks through volcanism and diastrophism. When igneous or sedimentary rocks are buried deep inside the Earth, they face high heat and pressure. This changes their minerals and structure, creating new rocks with different properties.
