- metamorphism
- the process in which rock changes into meta morphic rock because of chemicle processes or changes in tempature and pressure.
- chemical sedimentary rock
- sedimentary rock that form6s when minerals precipatate from a solution or settle from a suspension.
- mafic
- describes igneous rock that is rich in magnesium and iron that is generally dark in color.
- felsic
- describes igneous rock that is rich in feldspars and silica that is generally light in color.
- nonfoliated
- the metamorphic rock texture in which mineral grains are not arraged in plains or bands.
- igneous rock
- rock that forms when magma cools and solidifies.
- extrusive igneous rock
- rock formed from the cooling and solidification of lava at earth's surface.
- regional metamorphism
- a change In texture, structure, or chemical composition of a rock due to changes in tempature and presure over a large area,
- contact metamorphism
- a change In texture, structure, or chemical composition of a rock due to contact with magma.
- cementation
- the process in which minerals precipitate into pore spaces between sediment grains and bind together to form rock.
- intrusive igneous rock
- rock formed from the cooling and solidification of magma beneath earth's surface.
- rock cycle
- the series of processes in which rock forms, changes from one form to another, is destroyed and forms again by geological processes.
- foliation
- the metamorphic rock texture in which mineral grains are arranged in plains or bands.
- clastic sedimentary rock
- sedimentary rock thet froms when fragments of preexsiting rocks are compacted or cemented together.
- 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.
- 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.
- organic sedimentary rrock
- sedimentary rock that froms from the remains of plants or animals.
