The process of metamorphic rock
WebbMetamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock ( protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical changes. Webb935K views 10 years ago Geology In this video, we examine metamorphic rocks, including a look at how they form as a result of exposure to intense heat and/or pressure. We will also discuss...

Metamorphic rocks form when high temperatures and pressure act on a rock to alter its physical and chemical properties (metamorphism means 'to change form'). These conditions often stretch, twist and fold the rock as it cools.
