Question 1: Choose the listing that shows the rocks in increasing degrees of metamorphism (from lower- to higher-grade). migmatite, metaconglomerate, gneiss with mica, gneiss without mica metaconglomerate, gneiss with mica, gneiss without mica, migmatite metaconglomerate, gneiss with no mica, gneiss with mica, migmatite gneiss with no mica, gneiss with mica, migmatite, metaconglomerate It makes no difference; they're all examples of high-grade metamorphism. Question 2: What is the protolith of marble? quartz sandstone chert phyllite gypsum limestone Question 3: Identify the FALSE statement: Hydrothermal fluids may consist of hot water, steam, and supercritical fluid. are chemically active solutions, not pure water. change a rock's chemical composition, a process known as exhumation. can be derived from groundwater or magma, or can be the product of metamorphic reactions. can pick up some dissolved ions and drop off others as they circulate through a rock. Question 4 : Which of the following locations could not possibly be part of a shield?

Hawaii Canada Southern Greenland Siberia India Question 5: Identify the FALSE statement: A metamorphic rock may be composed of different minerals than its protolith. may have developed metamorphic texture of interlocking grains. cannot be formed below 1200 ° C. took thousands to millions of years to develop. may have preferred mineral orientation caused by differential stress. Question 6: Identify the FALSE statement: Extremely high heat of metamorphism may be as high as 1200 ° C. drives off water, causing high-grade metamorphic rocks to be drier than low-grade. is necessary to form migmatite. is necessary to form chlorite. causes mica to react, lose its identity, and become feldspar or some other water-free mineral. Question 7: Mylonite forms by recrystallization in a fault zone. is produced by shear stress on softened rock.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
