Earth Science Contact Metamorphism

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 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

What happened to the temperature and pressure if the rocks are buried down deep?

• increases

• decreases

• remain constant

• intermittently degrading

What is the process of changing the characteristics of a rock caused by changes in temperature, pressure, or volatile content?

• metamorphism

• lithification

• recrystallization

• rock cycle

Which of the following statements is not true about metamorphism?

• Metamorphism usually occurs during burial, tectonic movements, heating and presence of chemically active fluids.

• Metamorphism can range from slight to considerable changes in the parent rock.

• Metamorphism occurs when there is an increase in temperature and pressure which results to melting of rocks.

• Metamorphism of the protolith changes the texture and mineralogy of the original rock.

What will happen if the the temperature-pressure conditions exceeds the requirement for metamorphism?

• Rocks will melt and form igneous rocks.

• Rock will be changed into another metamorphic rock.

• Rocks will begin to weather and undergo erosion.

• Rocks will be compacted and cemented by heat.
