  1. 3.1 THE ROCK CYCLE SHOWS HOW ROCKS CHANGE Ch. 3: Rocks~Rocks change into other rocks over time~ http://www.youtube.com/watch?v=1_fmgivwQKw

  2. Vocabulary • ROCK • A naturally formed solid that is usually made up of one or more types of minerals • ROCK CYCLE • The set of natural processes that form, change, break down and re-form rocks • MINERALS • A substance that forms in nature, is a solid, has a definite chemical makeup, and has a crystal structure.

  3. Most Rocks are made of Minerals = = Crystal structure

  4. Most Rocks are made of Minerals • Rocks are made of different amounts of minerals calcite OBSIDIAN COAL LIMESTONE No Minerals No Minerals

  5. Our World is Built of Rocks • Earth is built almost entirely of rocks • What do you see when you look at the Earth’s surface? • Solid and Molten Rock (between crust and metallic core)

  6. Rocks are used for: Buildings (houses & skyscrapers)

  7. Rocks are used for: Sources of Metal (Fe, Al, Cu)

  8. Rocks are used for: Statues and Other Art

  9. Rocks are used for: Base for Pavement(Roads and Highways)

  10. Rocks in the World Around Us Granite Granite Limestone

  11. Rocks Change as they Move Through the Rock Cycle http://www.neok12.com/php/watch.php?v=zX616a577c597f7c784c720a&t=Types-of-Rocks • Rock Cycle=no beginning or end (continuous) http://www.bbc.co.uk/schools/ks3bitesize/science/environment_earth_universe/rock_cycle/activity.shtml http://www.geolsoc.org.uk/gsl/pid/3892;jsessionid=8B83B75B0CCE65419D96795CA0287503 http://www.youtube.com/watch?v=ehcshoYIIM4&feature=related

  12. Rock Types: Igneous Rock • Forms when molten rock cools to a solid • On Earth’s surface or within

  13. Rock Types: Sedimentary Rocks • Forms when pieces of rock, plants, or other loose materials get together • Carried by or

  14. Rock Types: Metamorphic Rocks • Forms from or pressure • Eventually raised to the surface

  15. Rocks in the Crust • 95% • metamorphic and igneous • 5% • sedimentary
