Detailed explanation-1: -Rock will be changed into another metamorphic rock.
Detailed explanation-2: -Regional metamorphism takes place under high temperature and pressure conditions that may extend over large areas. Regional metamorphism results in intense alteration of the mineralogy and texture of rocks, usually to the point where original sedimentary structures are destroyed.
Detailed explanation-3: -During metamorphism, protolith chemistry is mildly changed by increased temperature (heat), a type of pressure called confining pressure, and/or chemically reactive fluids. Rock texture is changed by heat, confining pressure, and a type of pressure called directed stress.
Detailed explanation-4: -Deep inside the Earth, intense heat and pressure can change rocks into entirely new metamorphic rocks. In fact, the conditions are so extreme, they can change the rock’s texture, color, and the shape of its crystals. Even the rock’s minerals are broken down and new ones are formed.
Detailed explanation-5: -Conditions like these are found deep within the Earth or where tectonic plates meet. Process of Metamorphism: The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks.
