Rock that forms when existing rock is altered

Metamorphic

Rock that forms when magma or molten rock cools & hardens

Igneous Rock

Simplified pattern that illustrates the order in which minerals crytallize from cooling magma according to chemical composition

Bowen’s reaction series

Series of process in which rock forms, changes from one type to another, is destroyed, and forms again by geological process

Rock Cycle

Rock that forms when deposits of dirt and rock are cemented and harden

Sedimentary

A measure of the tendency of a chemical compound to maintain the original chemical composition rather than to break down to form a different chemical

Atomic Restructuring

Huge igneous rock structures have weakness call

Joints

What does not change the form of existing rock

light (pressure, heat, chemicals do!)

The name of this rock means “from fire”

Igneous

The name for this type of rock means “changed form”

Metamorphic

Rock that forms from the remains of plants and animals

Organic Sedimentary

The process in which the volume & porosity of a sediment is decreased by the weight of overlaying sediment

Compaction

Rock that forms when minerals precipitate from a solution or settle from suspension

Chemical sedimentary

Process in which precipitate into pore spaces between sediment grain, binding them to form rocks

Cementation

Rock that forms when fragments of pre-existing rocks are compacted or cemented

Clastic Sedimentary

Rock that forms from the cooling & solidification of magma beneath the earth’s surface

Intrusive Igneous Rock

Mama or igneous rock that is rich in feldspar & silica and generally light in color

Felsic

Magma & igneous rock that is rich in magnesium & iron and generally dark in color

Mafic

Rock that forms when magma cools & solidifies

Igneous

Rock that forms from the cooling & solidification of lava at the Earth’s surface

Extrusive Igneous

The process in which one type of rock changes into another because of chemical processes or changes in temp or pressure

Regional Metamorphism

A change in texture, structure or chemical composition of rock because of changes in temperature & pressure over long periods of time

Metamorphism

A rock texture in which mineral grains are arranged in planes or bands

Foliation

A rock texture in which mineral grains are NOT arranged in planes or bands

nonfoliated

A change in the texture, structure, or chemical composition of rock due to contact with magma
