| ore | mineral containing something that can be useful & soldand |
| mineral | inorganic solid materials found in nature |
| gems | minerals that can be cut & polished |
| rock | formed of 2 or more minerals |
| crystal | solids w/ repeating patterns of atoms |
| foliated rocks (slate, shist) | metamorphic rocks w/ distinct bands of minerals heated & squeezed in parallel layers |
| nonfoliated rocks (marble) | metamorphic rocks (quartzite, marble, soapstone) no distinct bands or layers |
| organic rocks | form from dead plants & animals - compressed |
| metamorphic rocks | rocks formed when older rocks are heated and/or squeezed |
| sediment | pieces of broken rocks, shells, mineral grains |
| magma | melted rock material inside the Earth |
| lava | when melt reaches the Earth's surface |
| erosion | processes that break down rocks (weathering) and the processes that carry away the breakdown products |
| igneous rocks | produced when melted rock from inside Earth cools & hardens on or under Earth's surface |
| intrusive igneous rocks | form when melt occurs below Earth's surface |
| extrusive igneous rocks | when melted rock material cools on the Earth's surface |
| inorganic rocks | form when mineral rich water evaporates & other chemical processes |
| intrusive (basalt) & extrusive (granite) | classification of igneous rocks |
| detrital; organic; chemical | classifications of sedimentary rocks |
| foliated & non-foliated | classifications of metamorphic rocks |
| basalt, obsidian | igneous intrusive |
