| cementation | hardening and welding of sediments; last stage in the formation of sedimentary rock |
| compaction | reduction of pore space between individual particles as a result of overlying rocks or tectonic movements |
| sediment | any loose material that has settled, deposited from suspension in water, ice or air (ex: clay, mud, silt, sand, gravel or pebbles) |
| non-foliated | metamorphic rocks that have no cleavage; like quartz and marble |
| foliated | metamorphic rocks created as a result of directed pressure like mica and chlorite |
| extrusive | igneous rocks formed on the earth's surface; fine grained like basalt |
| intrusive | igneous rocks formed beneath the earth's surface; coarse grained rocks like granite |
| rock cycle | sequence of events involving the formation, change and destruction and reforming of rocks; it is a closed system |
| rock | part of the earth's crust made of minerals and/or materials of organic matter consolidated/sqished into a hard mass |
| metamorphic rock | rock changed in structure, composition, pressure, heat or chemically active fluids after original formation |
| sedimentary rock | rock formed from the accumulation and sedimentation of deposits from water, wind, ice or gravity |
| igneous rock | rock that is formed from cooling magma/lava |
