What are intrusive rocks?
100
The two types of metamorphic rock
What are foliated and nonfoliated?
100
These processes lead to the formation of sediment
What are weathering and erosion?
100
Molten rock that cools and hardens
What are igneous rocks?
200
The two processes that help to get the materials needed to make detrital sedimentary rocks
What are weathering and erosion?
200
Rocks that cooled so quickly that few or no mineral grains formed are examples of this type of rock
What are extrusive igneous rocks?
200
These types of metamorphic rocks are those in which the minerals have been flattened and pushed down into parallel layers
What are foliated metamorphic rocks?
200
Heat and pressure cause rocks to change into this type of rock
What is metamorphic?
200
High heat or pressure transforms rocks into these kinds of rocks
What are metamorphic rocks?
300
The three forces that help to FORM detrital sedimentary rocks?
What are deposition, compaction and cementation?
300
The name for dense, dark-colored igneous rocks
What basaltic igneous rocks?
300
These type of metamorphic rocks do not display layers. Rather, they are massive structures with no obvious banding. The mineral grains grow and rearrange, but they don't form layers.
What are non-foliated metamorphic rocks?
300
Deposition, compaction and cementation help to form this type of rock
What is sedimentary rock?
300
Particles of rock, shell, and bone are deposited in layers and compressed to form this type of rock
What are sedimentary rocks?
400
These types of sedimentary rocks are formed when dissolved minerals come out of solutions
What are chemical sedimentary rocks? (Chemical sedimentary rocks are not made from pieces of pre-existing rocks)
400
Light-colored rocks of lower density than basaltic igneous rocks are called this
What are granitic igneous rocks?
400
Two examples of foliated metamorphic rocks
What slate, shale, and gneiss? (need to have 2 of the 3)
400
Intense heat from this underground causes rocks to melt
What is magma?
400
The most common rocks on Earth, but because most of them exist below the surface, you might not have seen too many of them
What are igneous rocks?
500
Rocks made of the remains of once-living things are this type of sedimentary rock
What are organic sedimentary rocks?
500
This type of igneous rock is mostly found along the Pacific Rim
What are andesitic igneous rocks?
500

What are quartzite, marble and anthracite coal? (must have 2 of 3)
500
Volcanic activity forms this type of rock
What is an igneous rock?
