The process when sedimentary rock pieces are squeezed together.
What is compaction?
100
The two conditions in which metamorphic rock forms.
What is high heat and pressure?
100
This is melted rock within the Earth's crust.
What is magma?
100
This rock is formed when magma is pushed up from the mantle into the cool crust.
What is igneous rock?
200
Magma that hardens within the Earth's crust.
What is intrusive rock?
200
These are the three groups that sedimentary rocks are classified into.
What is clastic, organic, and chemical?
200
This kind of metamorphic rock forms when grains in the rock line up into stripes.
What is foliated metamorphic rock?
200
When magma is pushed up through the Earth's surface from explosion or by flowing from cracks in the Earth's surface, it is called this.
What is lava?
200
This rock forms through a process of weathering, erosion, deposition, compaction, and cementation.
What is sedimentary rock?
300
The rate of cooling determines this in an igneous rock.
What is texture or crystal size?
300
This kind of sedimentary rock is formed from minerals dissolved in water.
What is chemical sedimentary rocks?
300
This kind of metamorphic rock forms when mineral grains are arranged randomly.
What are nonfoliated metamorphic rocks?
300
This is the natural process of breaking rocks into smaller pieces through freezing, thawing, moving ice or flowing water.
What is weathering and erosion?
300
This rock forms deep in the Earth's crust from high heat and pressure being applied to existing rocks.
What is metamorphic rock?
400
These types of igneous rock are coarse in texture.
What is intrusive rock?
400
This kind of sedimentary rock is made from sediments and rock pieces that were weathered, transported and deposited in layers, with large pieces of rock still visible.
What is clastic sedimentary rock?
400
In respect to layers, metamorphic rocks are classified in two groups by geologists.
What are foliated and nonfoliated metamorphic rocks?
400
This is the movement of sediment to a new location.
What is deposition?
400
These are the main causes of metamorphism.
What is heat and pressure?
500
This type of igneous rocks are fine-grained or smooth in texture.
What is extrusive rock?
500
What are two uses for sedimentary rocks?
What are building and tools.
500
What are two uses for metamorphic rocks?
What are buildings and sculptures?
500
This happens when layers of sediment are glued together by dissolved minerals?
