Sediment undergoes three processes to form sedimentary rocks.
What are deposition, compaction, and cementation?
100
Deep underground.
Where does most metamorphic rock form?
100
The series of processes that change rock from one type to another.
What is the rock cycle?
200
Determines how the three major rock groups are named.
What is the way rocks are formed?
200
This is the most common extrusive rock.
What is basalt?
200
This is a denser, more compact version of slate.
What is shale?
200
Metamorphic rocks that have their grains arranged in parallel bands.
What is foliated?
200
This kind of rock forms when minerals that are dissolved in a solution crystallize on Earth's surface.
What are chemical rocks?
300
The characteristics geologists use to identify rocks.
What are mineral composition, texture, and color?
300
Igneous rock undergoes this process to form sediment
What is erosion?
300
A type of organic rock.
What is coal or limestone?
300
Igneous, sedimentary and other metamorphic rocks.
What are the types of rock that can form metamorphic rock?
300
This began as coral and can be found on continents.
What is limestone?
400
The minerals that make up most of Earth's crust.
What are rock-forming minerals?
400
Extrusive and intrusive rock.
What are the two ways igneous rock can be classified?
400
The process that presses sediments together.
What is compaction?
400
This collision produces high pressure that can push rock toward the mantle or fold to create metamorphic rock.
What is plate movement?
400
Conglomerate, sandstone, and limestone.
What are sedimentary rocks?
500
A coarse-grained igneous rock that is generally light-colored with a composition that includes quartz and feldspar.
What are the three ways geologists classify granite?
500
This type of igneous rock forms when magma cools beneath Earth's surface and hase larger crystals.
What is intrusive rock? (an example is granite)
500
A sedimentary rock that forms when rock fragments are squeezed together.
What is a clastic rock?
500
In this process, metamorphic rock could be exposed and worn away. Particles move to another place where they are deposited. Then compaction and cementation could change the sediment into sedimentary rock.
What is erosion?
500
This rock has large crystals surrounded by smaller crystals.
