- intrusive igneous rock
- rock formed from the cooling and solidification of magma beneath the Earth's surface
- metamorphism
- The process in which one type of rock changes into metamorphic rock because of chemical process or changes in temperature and pressure.
- contact metamorphism
- a change in the texture, structure, or chemical composition of a rock due to the contact with magma.
- extrusive igneous rock
- rock , formed from material that has erupted onto the earth's surface
- nonfoliated
- the metamorphic rock texture in which mineral grains are not arranged in planes or bands.
- organic sedimentary rock
- sedimentary rock taht forms from the remains of plants or animas
- felsic
- any light-colored igneous rock containing large abounts of feldspar and Silica
- cementation
- the process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock
- Rock cycle
- sequence of events in which rocks are formed, destroyed, altered, and reformed by geological processes
- igneous 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.
- compaction
- The process in which sediment is squeezed and in which the size of the pore space between sediment grains is reduced by weight and pressure of overlying layers
- chemical sedimentary rock
- sedimentary rock that forms when mnierals precipitate from a solution or settle from a suspension
- mafic
- rocks that contain a large amount of Magnesium and iorn, the cause of it's dark black color
- regional metamorphism
- a change in the texture, structure, or chemical composition of a rock due to the changes in temperature and pressure over a large area, generally as a result of tectonic forces.
- Bowen's reaction series
- the simplified pattern that illustrates the order in which minerals crystalize from cooling magma according to thier chemical composition and melting point
- foliation
- The metamorphic rock texture in which mineral grains are arranged in planes or bands.
