Miscellaneous
100
Magma that hardens on the Earth's surface.
What is extrusive rock?
100
This percent of the Earth's surface is sedimentary rock, but only this percent of the Earth's crust is sedimentary rock.
What is 75 percent and 5 percent?
100
The two conditions in which the metamorphism of rock occurs.
What is regional and contact metamorphism?
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 over millions of years within the Earth's crust.
What is intrusive rock?
200
These are the two groups that sedimentary rocks are classified into.
What is clastic and chemical?
200
This kind of metamorphism occurs when magma rises through the Earth's crust and touches existing rock. the hot magma then "bakes" the rock making it metamorphic.
What is contact metamorphism?
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 from materials from the surface of the Earth.
What is sedimentary rock?
300
The rate of cooling determines this in an igneous rock.
What is texture?
300
This kind of sedimentary rock is formed from minerals dissolved in water.
What is chemical sedimentary rocks?
300
This kind of metamorphism occurs in large areas around plate boundaries and most metamorphic rocks form this way.
What is regional metamorphism?
300
This is the natural process of breaking rocks into smaller pieces through freezing, thawing, moving ice or flowing water.
What is weathering?
300
This rock forms deep in the Earth's crust from magma or around plate boundaries.
What is metamorphic rock?
400
These types of igneous rock are course in texture.
What is intrusive rock?
400
This kind of sedimentary rock is made from sediments that were weathered, transported and deposited in layers.
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 erosion?
400
These are the main causes of metamorphism.
What is heat and pressure?
500
This type of igneouse rocks are fine-grained or smooth in texture.
What is extrusive rock?
500
Building, agriculture, energy and studying of the Earth.
What are uses of sedimentary rock?
500
This kind of metamorphic rocks have bands, or layers that you can see.
What is foliated metamorphic rocks?
500
This happens when layers of sediment is built up over many years.
What is sedimentation?
500
This kind of metamorphic rock does not have bands or layers that you can see.
What is nonfoliated metamorphic rock?
