Answer:

Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure of 100 megapascals or more, causing profound physical or chemical changes
