What is magma?
Molten rock beneath Earth's surface.
100
What is weathering?
This process produces rock and mineral fragments.
100
What are metamorphic rocks?
These form when preexisting rocks are exposed to increases in temperature and pressure and to hydrothermal vents.
100
What is the Rock Cycle
Cooling and crystallization, igneous rocks, uplift, weathering and erosion describe a path along this.
100
What are ways igneous rocks are used in industry?
Countertops, floors, grave markers, monuments.
200
What is Bowen's Reaction Series?
This defines the order in which minerals crystallize from magma.
200
What is erosion?
This process removes surface materials and transports them from one location to another.
200
What is texture in metamorphic rocks?
Foliated and Nonfoliated are the two types of this.
200
What are sedimentary, igneous, and metamorphic?
These are the three types of rocks.
200
What is fractional crystallization?
This is the process in which different mineral crystallize from magma at different temperatures, removing elements from magma.
300
What are extrusive rocks?
These types of rocks form under conditions of fast cooling, generally above Earth's surface.
300
What is clay?
This clastic sediment has the smallest grain size.
300
What are regional, contact, and hydrothermal?
These are the three main types of metamorphism.
300
What is igneous rock?
This type of rock is formed when magma cools and crystallizes.
300
What is porphyritic texture?
This texture of igneous rocks is characterized by large, well-formed crystals surrounded by finer-grained crystals of the same or different minerals.
400
What are intrusive rocks?
These types of rocks crystallize inside Earth?
400
What is graded bedding?
This type of grading occurs when sediment gets deposited as the energy of the water decreases.
400
What are minerals?
During metamorphism, the ___________ in a rock change into new ____________ that are stable under the new temperature and pressure conditions.
400
What is metamorphic rock?
This type of rock forms when sedimentary rocks are exposed to increased heat and pressure.
400
What is vesicular?
This texture is spongy looking, like in pumice.
500
What are fine-grained crystals?
This size of crystals are formed when magma cools quickly.
500
What is lithification?
This is the result of compaction and cementation of clastic sediments.
500
What are hydrothermal quartz vents.
Native gold, silver, and copper deposits tend to occur in these.
500
What is sedimentary rock?
This type of rock is formed when igneous rocks undergo uplift and weathering and erosion.
500
What are evaporites?
These are layers of chemical sedimentary rocks that form when concentrations of dissolved minerals in a body of water reach saturation due to the evaporation of water.
