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