Which of the following statements describe metamorphism?

• process of rock formation

• change in rock formation

• process which involves changes

• change that takes place within body of rock once expose to different conditions

Which of the following metamorphism is affected by heat and reactive fluid?

• contact only

• regional only

• both contact nor regional

• neither contact nor regional

Which of the following led to the formation of deformed rocks with foliation?

• volume of air entering the rocks

• temperature and rising of magma

• temperature and volume of minerals

• pressure and recrystallization of minerals

What is the effect of heat and pressure in rocks as there is an increase in depths?

• foliation surfaces shine

• low -grade metamorphism

• grain size becomes coarse

• increase in mineral alignment

Which of the following is the main factor in the process of regional metamorphism?

• air

• water

• pressure

• temperature

Which type of metamorphism is caused by high temperature and high pressure enacted over a large volume of crust?

• burial

• contact

• regional

• pyroclastic

2) Which of the following principal agents of metamorphism?

• a.Pressure                                                                         

• b. Heat and Electricity                                                        

• c. Temperature and Pressure

• d. Heat and magma 

How do temperature and pressure affect metamorphism?

• Pressure and temperature increase as you go up to the crust.

• The deeper the rock depths, the higher the pressure and temperature.

• Foliation happens as there is an increase in the pressure and temperature.

• Magma cannot bake the surrounding rocks due to the difference in temperature.

It occurs when rocks are buried to depths of several hundred meters.

• dynamic metamorphism

• contact metamorphism

• burial metamorphism

• shock metamorphism

Which is TRUE about regional metamorphism?

• It occurs over small areas that experience differential stress.

• It occurs when two bodies of rockslides past each other along faults.

• It occurs over large areas that experience differential stress.

• All of these explain regional metamorphism.
