Igneous is bliss
True or false: Magma is molten rock that has reached the earth's surface.
False
What is compaction?
when sediment is pushed together by the weight of water and other sediment pushing down on it.
The rock with distinct bands of minerals that have been heated and squeezed into parallel layers
Foliated
What is the name of the two processes that create sedimentary rocks
Lithification
What rocks form from existing rocks that have been heated and squeezed?
Metamorphic rocks
What are the names of the mineral contents used to classify igneous rocks?
felsic or mafic
What type of sedimentary rock forms from non-living matter that has died and been compressed?
Carbonate
What is regional metamorphism?
When large regions of the earth's crust are affected by high temperatures and high pressures
What are the 5 basic processes that are involved in the rock cycle?
Magma; igneous rocks; sediments; sedimentary rocks; metamorphic rocks
What is dynamic metamorphism?
Metamorphism that is produced by mechanical force (i.e. pressure)
What type of rocks form when magma cools beneath the earth's surface?
Intrusive
What is cementation?
When sediment is glued together.
What is the type of rock without distinct layers or bands.
Nonfoliated
To what type of rock can all rocks be traced?
Igneous rocks
True
What type of rock forms on the Earth's surface?
Extrusive
What type of sedimentary rock forms from the evaporation of a solution?
Chemical
How are metamorphic rocks formed?
They are formed as a result of intense heat and pressure being applied to igneous rock, sedimentary rock, and other metamorphic rock.
Name the process by which one rock type changes into another.
The rock cycle
True or false: Rocks are classified by texture and color.
False: They are classified by how they form.
Most intrusive rocks have _________________ crystals because they cooled _____________.
Large; slowly
What type of sedimentary rock is the most common? (clastic, chemical or carbonate)
Clastic
The metamorphism that occurs when heat of magma comes into contact with existing rocks.
contact metamorphism
True or false: All rocks go from an igneous rock to a sedimentary rock to a metamorphic rock.
False
What are sediments?
particles of minerals, rock fragments, shells, leaves, and the remains of once-living things
