How is the metamorphic rock formed
Metamorphic 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 of 100 megapascals (1,000 bar) or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid st… Web26 okt. 2014 · Metamorphic rock facts Metamorphic rocks are formed from existing rocks Metamorphic rocks are pre-existing rocks on the earth's surface that change in composition and density over a long period of time under the influence of pressure and heat.
