  3. Definition • A rock is a solid mixture of minerals and other materials. • A mineral is a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition. SNIFC

  4. 3 Types of Rocks • Sedimentary rocks forms from particles from other rocks, or remains of plants and animals that are compacted and cemented together. Fossils are found in these rocks. • Igneous rocks form when magma or lava cools. • Metamorphic rocks form when a rock is changed by heat and pressure.

  5. To identify a mineral: SNIFC it out! SNIFC • Solid • Cannot be a liquid or a gas • Naturally Occurring • Found in nature, not man-made • Inorganic • Is not alive and never was, non-living (generally not made from Carbon) • Fixed composition • Has a chemical formula, most are formed from compounds of two or more elements, some minerals consist of one element ex. Au • Crystal Form • A definite structure in which atoms are arranged

  6. Identifying Minerals • Color • Streak – color of a mineral’s powder • Luster – way a mineral reflects light • Density – mass per unit volume • Hardness – uses a scratch test • Crystal Systems • Cleavage & Fracture – cleavage splits easily along flat surfaces; fracture breaks in a irregular way • Special Properties – magnetism, fluorescence

  7. Mineral 4) gemstone • Rock 5) ore • Crystal or polyhedron
