  1. Rocks & Minerals ROCKS

  2. Rocks are made of more than one mineral Could have other substances comprising them Rocks blue.utb.edu/.../PHYS1417SPR00/Unit3Lec.html

  3. Rocks Classificationclassified by geologic process that formed them (origin of rocks) http://geology.com/rock-tumbler/tumbling-rough.shtml

  4. How were the rocks formed - magma - erosion and layering - heat and pressure Rock Classification

  5. Igneous rocks are formed from the cooling of magma or lava Lava is magma that reaches the earth’s surface Origin of rocks www.outreach.canterbury.ac.nz/.../igneous.jpg

  6. Sedimentary rocks formed from other rocks that are broken into small particles and moved by erosion (wind or water) particles are squeezed or cemented together Rocks are layered Origin of rocks www.energyinst.org.uk/education/glossary/

  7. Metamorphic rocks formed from other rocks pushed deep into the earth’s crust Pressure and heat cause them to change shape, color, grain and structure Origin of rocks http://www.classzone.com/books/earth_science/terc/content/visualizations/es0607/es0607page01.cfm?chapter_no=visualization

  8. Properties • Texture • Grain • Minerals • Color

  9. Texture is how a rock looks and feels texture in rocks is determined by the size, shape, and pattern of a rocks grains. Texture ocal.wasp.uwa.edu.au/.../rock/rock16.jpeg

  10. Size -- large, small Shape --smooth, rough, round jagged Pattern – rows, waves, swirls, beads or random patterns Grain http://www.union.edu/PUBLIC/GEODEPT/COURSES/geo-10/metamorphic.htm
