  1. Rocks and Minerals What you need to know but may have forgot!!

  2. All rocks have the POTENTIAL to go through the rock cycle!! PICK ME!!!!! http://www.holmes-arts.com/store/product_photos/rock_people.jpg

  3. The Rock Cycle Rocksandminerals4you.com

  4. Igneous rocks Once very hot magma Heat and pressure make the change Igneous Rocks Form inside the Earth or outside The earth crust http://stloe.most.go.th/html/lo_index/LOcanada2/204/images/2_4_5en.jpg

  5. Metamorphic Rocks Rocks that have changed due to intense heat and pressure Created from sedimentary, igneous or other metamorphic rocks. They are formed deep inside the earth. Heat, and pressure from the rock above flatten and bend the rock Formed deep within the earth! http://stloe.most.go.th/html/lo_index/LOcanada2/204/images/2_4_5en.jpg

  6. Sedimentary Rock Little pieces of rock, dirt, broken down and worn away by erosion Wash away down rivers, into lakes and oceans Layer on layer of these bits of earth are deposited on top of each other over time Pressure of more and more “sediments” –bottom layers turn into rock Starts on the crust and compacts and cements inside the earth http://www.fi.edu/fellows/fellow1/oct98/create/sediment.htm

  8. How might these rocks have gotten here? Look more closely at the Rock Cycle!! http://www.learner.org/interactives/rockcycle/diagram.html

  9. There are properties you can Test to determine the mineral

  10. Hardness Hardness http://www.minsocam.org/MSA/K12/properties/hardness.html These are common “tools” for testing hardness Mineralogical Society Minerals for Kids

  11. LUSTER Luster How the mineral reflects light! • What words can describe the luster? • Dull • Waxy • Glassy • Very shiny • Silvery • Shiny • Opaque • Reflective

  12. Cleavage Cleavage: when a rock or mineral breaks along flat , smooth Surfaces. Fracture: When a rock or mineral breaks into irregular rough surfaces Cubic cleavage New York State High School Regents Exam Prep

  13. Streak Test This is a test where you scratch the mineral against a porcelain This test tells you the color of the mineral

  14. Rock properties make them useful for different purposes. Rocks that can be cut into regular shapes are useful for buildings and statues Rocks that crumble easily are useful for making mixtures such as concrete and sheetrock.

  15. Identify two physical properties of minerals. • Describe how Elena can test the mineral she found for each of the physical properties that you identified in part (a).

  16. There are properties you can Test to determine the mineral
