Answer:
1. Metamorphism is the alteration of rock’s Chemical composition, mineral components and texture.
2. Metamorphic rocks are formed when rocks are subjected to significant changes in temperature and pressure.
3. Confining pressure is force exerted equally from all directions, whereas directed pressure is force exerted unequally in different directions.
4. In the presence of directed pressure, recrystallization may align minerals parallel to the force/stress applied on the rocks.
5. Regional metamorphism takes place where both high and temperatures are imposed over large parts of the crust and usually takes place in continental plate boundaries.
6. Contact metamorphism is the localized transformation or rocks near to igneous intrusions mainly as a result of high temperatures.
7. Other types of metamorphism are shock, burial, and high-pressure metamorphism.
8. Foliation is created by alignment of minerals under directed pressure.
9. Granoblastic rocks are contact metamorphic rocks composed mainly of crystals that grow in large size and distinct shapes.
10. Metasomatism occurs when the change in rock’s composition is due to interactions with fluids.
