  1. You throw away the outside and cook the inside. Then you eat the outside and throw away the inside. What did you eat? What goes up and down the stairs without moving? I run over fields and woods all day. Under the bed at night I sit not alone. My tongue hangs out, up and to the rear, awaiting to be filled in the morning. What am I?

  2. Miracle

  3. Lets review minerals • What are the 5 things a mineral has to be? • Which of these gives the minerals their physical properties • What are 6 identifying features of a mineral • Most rocks are made up of ___________ or more minerals • Name Three classes of minerals? • 1. • 2. • 3.

  4. What physical property am I looking at?

  5. Rocks & Minerals

  6. Rocks

  7. Poly-mineralic Mono-mineralic made of two or more minerals made of one mineral

  8. Most Rocks Are Poly-mineralic

  9. Three Classifications of Rocks are: igneous sedimentary metamorphic

  10. Sedimentary Igneous Metamorphic

  11. Sedimentary Rocks Key Concept #1 Most sedimentary rocks are made of pieces (sediments) ( clasts ) of other rocks. Image #2 Image #1

  12. Key Concept #2 Name two processes that form sedimentary rocks Compaction Cementation clasts held together by minerals (cement) the weight of overlying sediments forces particles together

  13. Key Concept #3 In what type of environment are most sedimentary rocks formed? watery

  14. Key Concept #4 Key Identifying Features of Sedimentary Rocks Strata Clear Layering of Sediments Image #3 Image #1 Image #2

  15. Key Concept #4 Key Identifying Features of Sedimentary Rocks Clasts pieces of other rocks Image #2 Image #1

  16. Key Concept #4 Key Identifying Features of Sedimentary Rocks Fossils the remains of once-living organisms Image #3 Image #1 Image #4 Image #2

  17. A to Z contest

  18. Igneous Rocks

  19. Igneous Rocks Key Concept #1 How are igneous rocks formed? the melting and solidification of magma

  20. Igneous Rocks: Key Concept #2 Name two places where igneous rocks form

  21. Volcanoes Rifts/Ridges

  22. Igneous Rocks: Key Concept #3 What determines crystal size?

  23. cooling time

  24. crystal size cooling time

  25. Large Crystals Indicate long cooling time Small Crystals Indicate short cooling time

  26. Igneous Rocks: Key Concept #4 What’s the difference between extrusive and intrusive igneous rocks?

  27. Intrusive Extrusive form on or near the surface (small crystals) form below the surface (large crystals)

  28. Igneous Rocks: Key Concept #5 Characteristics used to classify igneous rocks

  29. Key Concept #5 Characteristics used to classify igneous rocks texture glassy } extrusive fine

  30. Key Concept #5 Characteristics used to classify igneous rocks texture coarse } intrusive very coarse

  31. Key Concept #5 Characteristics used to classify igneous rocks color dark light

  32. Key Concept #5 Characteristics used to classify igneous rocks density low high

  33. Key Concept #5 Characteristics used to classify igneous rocks composition mafic contains Fe and Mg felsic contains Al

  34. Igneous Rocks: Key Concept #6 Key Identifying Features of Igneous Rocks

  35. Glassy Texture usually black in color Interlocked Grains the grains have been melted and are now physically connected

  36. Metamorphic Rocks

  37. Metamorphic Rocks Key Concept #1 How are metamorphic rocks formed? extreme heat and/or pressure

  38. Metamorphic Rocks Key Concept #2 If melting occurs, it is classified as an MELTING DOES NOT OCCUR! Igneous Rock

  39. Metamorphic Rocks: Key Concept #3 What is the difference between Regional and Contact Metamorphism?

  40. Regional Metamorphism Large geographic area Example: where mountains form

  41. Contact Metamorphism small geographic area Example: when rocks come in contact with magma

  42. Metamorphic Rocks: Key Concept #4 Key Identifying Features of Metamorphic Rocks

  43. Foliation Image #1 Image #2 banding of minerals usually black and white Image #3

  44. Distorted Structure folded layers Image #3 Image #1 Image #2

  45. Key Identifier Minerals Dark Red Color Garnet Shiny, flaky Mica
