The Rock Cycle
100
This is a solid mass of mineral matter that occurs naturally.
What is a rock?
100
This type of igneous rock forms when magma hardens and cools.
What is intrusive?
100
Rocks with many dark silicate minerals and plagioclase feldspar have this kind of composition.
What is basaltic?
100
Marble is this type of metamorphic rock.
What is nonfoliated?
100
Because of the processes that take place within this cycle, rocks can change from one type to another.
What is the rock cycle?
200
3 types of rock
What is igneous, sedimentary, and metamorphic?
200
This type of igneous rock forms when lava hardens and cools.
What is extrusive?
200
During the erosion and deposition processes, this size of sediments are carried and deposited the greatest distances.
What is small?
200
Gneiss is this type of metamorphic rock.
What is foliated?
200
All of the energy that drives Earth's rock cycle comes from these two sources.
What is Earth's interior and the Sun?
300
This type of rock forms when sediments are compacted and cemented together.
What is sedimentary?
300
Slow cooling produces igneous rocks with this kind of texture.
What is coarse-grained?
300
Because of the way they form, limestone and chert are classified as this type of sedimentary rock.
What is chemical?
300
Hydrothermal solutions cause recrystallization and an overall change in this.
What is composition?
300
Name 4 of the 8 processes that occur within the rock cycle
What is weathering, erosion, compaction, cementation, heat, pressure, melting, cooling.
400
This type of rock forms when magma or lava hardens and cools.
What is igneous rock?
400
An igneous rock that contains mostly pyroxene and olivine has this type of composition.
What is ultramafic?
400
Shale and breccia are examples of this type of sedimentary rock.
What is clastic?
400
Metamorphic rocks forms as a result of these two processes.
What is heat and pressure.
400
The processes that occur ON Earth's surface produce this type of rock.
What is sedimentary?
500
This type of rock forms as a result of heat and pressure.
What is metamorphic rock?
500
Granite is an example of this type of igneous rock.
What is intrusive?
500
Sedimentary rocks form as a result of these two processes.
What is compaction and cementation?
500
Large-scale folding of rock during the process of mountain formation is characteristic of this type of metamorphism.
What is regional?
500
What do silicates require in order for metamorphosis to occur, to change from sedimentary to metamorphic rock?
What is very high temperatures?
