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
deposition – the dropping off of eroded materials in a new location
erosion– the process of moving sediments by wind, water, ice and gravity
foliated – rocks that are composed of thin easily separable layers or bands
igneous rock - Rock formed when heated magma or lava cools and hardens
lava - A result of molten rock material pushed to Earth’s surface by volcanic action
lithification - The compaction and cementation of sediment into rock.
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
non-foliated – rocks that do not have a layered or banded structure.
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
weathering – the process of breaking rocks down into sediments
- • Extrusive rocks- Formed when molten rock reaches the Earth’s surface and cools.
Intrusive rock- Formed when magma cools underground forming rock
