WebOne ways rocks may change during metamorphism is by rearrangement of their mineral crystals. When heat and pressure change the environment of a rock, the crystals may respond by rearranging their structure. They will form new minerals that are more stable in the new environment. WebProcess of Metamorphism: The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks. New minerals are created …
