- Mafic
- describes magma or igneous rock the is rich in magnetism and iron and that is generally dark in color.
- Intrusive Igneous Rocks
- rock formed from the cooling and solidification of magma beneath Earth's Surface.
- Metamorphic rocks
- The rock that forms when existing rock is altered.
- volcano
- is a vent through which magma is exspelled
- Cementation
- the process in which minerals precipitate into pore spaces between sediment grains and bind sediments together from rock
- sill
- When magma flows between the layers of rock and hardens
- dike
- When magma solidifies
- Sediment
- Rocks, mineral crystals and organic matter that have been broken into fragments that are known as sediment.
- 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
- Compaction
- the process in which the volume and porosity of a sediment Is decreased by
- Rock Cycle
- The series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geological processes.
- intrusions
- From when Magma intrudes, or enters, into other rock masses and then cools deep inside Earth's crust.
- igneous rocks
- Means "from fire" It forms when magma or molten rock cools and hardens, Magma is called lava when it is exposed at Earth's surface.
- Chemical Stability
- is a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down on it's own.
- sedimentary rock
- When sediment deposits are compressed or cemented together and harden.
- Partial melting
- the process by which different minerals in rock melt at different temperatures
- Extrusive Igneous Rock
- rock that forms from the cooling and solidification of lava at Earth's surface.
- Felsic
- described magma or igneous rich that is rich in feldspar and silica and that is generally light in color.
- boatholiths
- are intrusion formations that spread over at least 100 km2 when they are exposed on Earth's surface
- Laccolith
- the base if the intrusion is parallel to the rock layer beneath it
