Metamorphic rocks


Metamorphosed (transformed) rocks are formed from all types of rocks as a result of the high temperatures, pressures and chemical environments to which rocks are exposed in the Earth's crust. The structure of the rocks adapts to new conditions that are different from the conditions under which they were formed. The resulting degree of transformation depends on the duration and magnitude of these factors.
