WebMetamorphicrock forms when the chemical composition of a rock changes because of heat and pressure. This change is called metamorphism. Metamorphism can happen to any kind of rock. Most metamorphism happens at temperatures between 150°C and 1,000°C. Some metamorphism happens at even higher temperatures. WebGeologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale.

WebMetamorphic: Metamorphic rocks form when existing rocks are subjected to intense heat and pressure, usually deep below the earth’s surface. These conditions change the original minerals of the rock into new minerals. Geologists classify metamorphic rocks according to how much they have been changed from the original, or parent, rock.
