- rock cycle
- the series of processes in which rock forms, changes from one type to another is destroyed and forms again by geological processes
- bowen's reaction series
- the simplifed pattern thet illustrates the order in which minerals crystallize from cooling magma according to their chemical composition and melting point
- felsic
- describes magma or igneous rock that is rich and feldspars and silica and is generally light in color
- intrusive igneous rock
- rock formed from the cooling and solidification of magma beneath earth's surface
- regioal metamorphism
- the type of metamorphism that occurs over a large area
- nonfoliated
- rocks that don't have bands or aligned minerals
- cementation
- the process in which minerals precipitate into pore spaces between sediment grains and bind sediment togetherto form rock
- chemical sedimentary rock
- sedimentary rock that forms when minerals precipitate from a solution or settle from a supension
- compaction
- the process in which the volume and porosity of a sediment is decreased by weight of overlying sediments as a result of burial beneath other sediments
- organic sedimentary rock
- sedimentary rock that forms from the remains of of plants and animals
- metamorphism
- the process by which heat, pressure, or chemical processes change 1 type of rock to another
- mafic
- describes magma or igneous rock that is rich in magnesium and iron and is generally dark in color
- igeous rock
- rock that forms when magma cools and solidifies
- clastic sedimentary rock
- sedimentary rock that forms when fragments of preexisting rocks are compacted or cemented together
- contact meamorphism
- a change in the texture, structure, or chemical composition of a rock due to contact with magma
- extrusive igneous rock
- rock that forms from the cooling and solidification of lava at earth's surface
- foliation
- metamorphic rock texture in which minerals grains are arranged in planes or bands
