- Intrusive Igneous Rock
- The magma that cools deep within the surface of the Earth.
- Compaction
- The process in which sediment is squeezed and in which the size of the pore space between sediment grains is reduced by the weight and pressure of overlying layers.
- Cementation
- The process in which sediments are glued together by minerals that are deposited by water.
- Chemical Stability
- A measure of the tendency of a chemical compound to maintain its original chemical composittion.
- Felsic
- Rock that forms from magma that contains a large portion of silica.
- Rock Cycle
- Geological forces and processes that cause rock to change form one type to another.
- Extrusive Igneous Rock
- Lava that cools at Earth's surface.
- Joints
- Evenly spaced zones of weaknesses in igneous rock.
- Organic Sedimentary Rock
- Sedimentary rock that forms from the remains of plants or animals
- Sedimentary Rock
- Rock formed by sediments of existing rock being compressed and heated.
- Chemical Sedimentary Rock
- Sedimentary rock that forms when minerals precipitate from solution or settle from suspension.
- Mafic
- Rock that forms from magma that contains lower portions of silica and is rich in iron and magnesium.
- Metamorphism
- The process in which one type of rock changes into metamorphic rock because of chemical changes in temperature and pressure.
- Bowen's Reaction Series
- A simplified pattern that explains the order in which minerals form as magma or lava solidifies.
- Igneous Rock
- Rock formed by the cooling of lava or magma.
- Metamorphic Rock
- Rock formed by the altering of existing rock.
- Clastic Sedimentary Rock
- Sedimentary rock that forms when fragments of preexisting rocks are compacted or cemented together.
