inorganic, solid material found in nature that always has the same chemical makeup, atoms arranged in an orderly pattern, and properties such as cleavage and fracture, color, hardness, streak and luster
rock – solid, inorganic material that is usually made of two or more minerals and can be metamorphic, sedimentary, or igneous crystal – solid material with atoms arranged in a repeating pattern gem – rare, valuable mineral that can be cut and polished ore – mineral resource that can be mined at a profit igneous rock – intrusive or extrusive rock that is produced when melted rock from inside Earth cools and hardens extrusive – igneous rocks that form when melted rock cools quickly on Earth’s surface intrusive – igneous rocks that form when melted rock cools slowly and hardens underneath Earth’s surface sedimentary rock – a type of rock made from pieces of other rocks, dissolved minerals, or plant and animal matter that collect to form rock layers metamorphic rock – new rock that forms when existing rock is heated or squeezed (heat & pressure) foliated – metamorphic rocks with visible layers of minerals nonfoliated – metamorphic rocks that lack distinct layers or bands rock cycle – diagram that shows how rocks are related to one another and how they change from one type to another |
