METAMORPHISM

1. It occurs when rocks are buried to depths of several hundred meters and form new low-grade rocks due to the temperature increase.

• CONTRACT METAMORPHISM

• BURIAL METAMORPHISM

• DYNAMIC METAMORPHISM

• REGIONAL METAMORPHISM

2. 2. It occurs when a meteorite hits the surface of earth & transfers a lot of heat to the place of impact, causing rocks to change.

• RETOGRADE METAMORPHISM

• DYNAMIC METAMORPHISM

• SHOCK METAMORPHISM

• REGIONAL METAMORPHISM

3. 3. It takes place mostly along mid-ocean ridges, where ocean water is heated by nearby magma to form hydrothermal.

• RYCRYSTALLIZATION

• RETOGRADE METAMORPHISM

• PROGRADE METAMORPHISM

• HYDROTHERMAL METAMORPHISM

4. It is the formation of new minerals from the pre-existing minerals due to heat.

• NEOCRYSTALLIZATION

• RYCRYSTALLIZATION

• PROTOLITH

• PLASTIC DEFORMATION

5. Property of minerals that have different structures but with the same chemical formula.

• ENDOMORPH

• POLYMORPH

• POLIOMORPH

• PHASE CHANGE

6. It takes place at approximately at 320 ºC–450 ºC and at moderate pressures.

• Low-grade metamorphism

• Intermediate metamorphism

• High-grade metamorphism

• Retograde metamorphism

7. 7. When water molecules from minerals are usually squeezed out, forming “drier” rocks.

• Retograde metamorphism

• Prograde metamorphism

• Plastic deformation

• Burial Metamorphism

8. 8. It refers to the change in mineral structure but with the same chemical formula.

• Phase Change

• Retograde Metamorphism

9. 9. It occurs when heat is transferred from igneous intrusions to nearby rocks.

• Burial Metamorphism

• Dynamic Metamorphism

• Thermal metamorphism

• Contract Metamorphism

10. It is a process where there is growth in size of mineral grains of pre-existing materials.

• Neocrystallization

• Phase Change

• Plastic Deformation
