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 Contact Metamorphism
