Rock multiple choice

1. In the process of metamorphic rock formation, what is recrystallization?
change in particle size
lining up of minerals in a given direction
melting of minerals
change in chemical elements

2. Metamorphism is defined as
compaction and cementation of rock fragments
changing of a rock by heat and/or pressure
crystallization of magma as it cools within Earth
evaporation of seawater and precipitating out of minerals

3. During metamorphism, high temperatures can allow atoms within mineral crystals to migrate, thus leading to a reorganization of crystals in metamorphic rocks.
True/False
4. Which metamorphic rock is made of metamorphosed sandstone?
marble
quartzite
amphibolites
phyllite

5. Which metamorphic rock is characterized by fine-sized grains and by the fact that it breaks easily into plates?
gneiss
schist
slate
metaconglomerate

6. Which metamorphic rock is shown in the image?
marble
phyllite
amphibolites
gneiss

7. How does the foliation of a metamorphic rock relate to the environment in which the rock formed?
Foliation is parallel to the orientation of the force that formed the rock.
Foliation is perpendicular to the orientation of the force that formed the rock.
Foliation is directly proportionate to the temperature that formed the rock.
Foliation is indirectly proportionate to the temperature that formed the rock.
8. Which metamorphic rock is commonly used for making statues?
gneiss
schist
marble
slate

9. A lava flow baking a rock is an example of contact metamorphism.
True/ False
10. Horizontal tectonic movements are responsible for regional metamorphism.
True / False
11. What is the process by which sediments are compacted into sedimentary rocks?
crystallization
lithification
erosion

12. Which of the following rock types can melt within the earth and later cool into an igneous rock?
sedimentary only
sedimentary and metamorphic only
sedimentary, metamorphic, or igneous

13. Which of Earth's systems drive the rock cycle?
tectonic system
hydrologic system
both of the above
