| Metamorphic rock | rock formed as heat or pressure causes existing rock to change in structure, texture, or mineral composition |
| Metamorphism | the process by which a rock's structure or mineral composition is changed by pressure or heat |
| Recrystallization | the process by which bonds between atoms in minerals break and re-form in new ways during metamorphism |
