Vocabulary notes
cementation - A process whereby compacted sediments bind and stick together and turn into rock
compaction - A process whereby sediments pack, crush, and settle under the action of gravity and pressure from overlying layers
metamorphic rock - Rock deep within Earth’s crust that has been exposed to extreme heat and pressure causing changes to its appearance, structure, and composition
recrystallization - A reaction in which the atoms of existing crystals within a rock are reorganized due to heat and/or pressure.
sedimentary rock - Rock formed when sediments deposited in layers, compact and cement together under pressure, over long periods of time
