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. 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. 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. When water molecules from minerals are usually squeezed out, forming “drier” rocks.
Retograde metamorphism
Prograde metamorphism
Plastic deformation
Burial Metamorphism
8. It refers to the change in mineral structure but with the same chemical formula.
Phase Change
Polymorph
Plastic deformation
Retograde Metamorphism
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
Recrystallization
11. In prograde metamorphism, it takes place when temperature and pressure _________.
12. This process requires the addition of hydrothermal fluids or water.
13. Occurs when mineral grains soften and deform at high temperatures.
14. Occurs when two bodies of rock slide past each other along faults, where some rocks are heated and pulverized to form new rocks. Example of this is myolite.
15. It occurs over large areas that experience stress, such as in convergent boundaries, where one tectonic plate goes under another tectonic plate.
