Rock Cycle

the series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes

Bowen's Reaction Series

the simplified pattern that illustrates the order in which minerals crystallize from cooling magma according to their chemical composition and melting point

Igneous Rock

rock that forms when magma cools and solidifies

Intrusive Igneous Rock

rock formed from the cooling and solidification of magma beneath Earth's surface

Extrusive Igneous Rock

rock that forms from the cooling and solidification of lava at Earth's surface

Felsic

describes magma or igneous rock that is rich in feldspars and silica and that is generally light in color

Mafic

describes magma or igneous rock that is rich in magnesium and iron and that is generally dark in color

Compaction

the process in which the volume and porosity of a sediment is decreased by the weight of overlying sediments as a result of burial beneath other sediments

Cementation

The process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock

Chemical Sedimentary Rock

sedimentary rock that forms when minerals precipitate from a solution or settle from a suspension.

Organic Sedimentary Rock

sedimentary rock that forms from the remains of plants or animals

Clastic Sedimentary Rock

sedimentary rock that forms when fragments of preexisting rocks are compacted or cemented together

Metamorphism

the process in which one type of rock changes into metamorphic rock because of chemical processes or changes in temperature and pressure

Contact Metamorphism

a change in the texture, structure, or chemical composition of a rock due to contact with magma

Regional Metamorphism

a change in the texture, structure, or chemical composition of a rock due to changes in temperature and pressure over a large area, generally as a result of tectonic forces

Folliation

the metamorphic rock texture in which mineral grains are arranged in planes or bands

Nonfoliated

the metamorphic rock texture in which mineral grains are not arranged in planes or bands.
