WebMetamorphic 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. During this process, the rock remains mostly in the solid …

WebMetamorphic rock is igneous or sedimentary rock that has been heated and squeezed. [1] It can erode into sediment or melt into magma. It is formed under extreme pressure and temperature deep inside mountain chains . Sedimentary rock is compacted sediments which can come from any of the other rocks, [1] plus remains of living things.
