What are Metamorphic Rocks?
Rocks that have undergone significant heat and pressure are known as metamorphic rocks. Due to these circumstances, the minerals in rocks rearrange and recrystallize, creating a new rock with differing characteristics from the original rock. Any type of rock, including igneous and sedimentary rocks, can undergo metamorphism. They can also develop as a result of tectonic plate collisions, which subject the rock to extreme pressures and temperatures. Regional Metamorphism and Dynamothermal Metamorphism are the two basic forms of Metamorphism.
