  1. Rocks and Minerals Study Guide

  2. What are minerals? • There are 5 things that characterize minerals. • Inorganic • Solid • Chemical composition • Crystalline structure • Naturally occuring

  3. What are two ways minerals form? • Minerals form from… • hot molten rock (magma or lava): When minerals from from the molten rock, it cools and forms the mineral. • the evaporation of hot water solutions: When minerals form from solutions, the solution evaporates, and leaves the mineral behind.

  4. Moh’s Hardness Scale • Measures the hardness or scratch resistance of minerals

  5. What can minerals be used for? • Jewelry, cosmetics, batteries • Hinges, clocks, wiring • Mirrors, sporting equipment, light bulbs • Watches, pencils, tiles • Appliances, matches, containers • Furniture, computers, phones

  6. What is the rock cycle? • The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time

  7. What are rocks? • A naturally occurring solid mixture of one or more minerals that may include organic matter

  8. What processes change rock? • Changing temperature and pressure • Erosion, deposition, cementation • Melting and cooling

  9. How do rocks form? • Igneous rocks form when hot liquid magma cools into solid rock • Metamorphic rock forms when rock is exposed to high temperature and pressure and the crystal structures of the minerals in the rock change to form new minerals • Sedimentary rock forms when rock is weathered, eroded, deposited, buried,and cemented

  10. Classes and subclasses of rock
