  3. Rock Mugshots$100 Q • Black or brown glassy rock

  4. Rock Mugshots $100 A • Igneous--obsidian

  5. Rock Mugshots$200 Q • Tiny particles cemented together by calcite, silica, or iron oxides.

  6. Rock Mugshots$200 A • Sedimentary--sandstone

  7. Rock Mugshots $300 Q • Parent rock is shale; extremely fine texture and splits cleanly along its rock planes

  8. Rock Mugshots$300 A Metamorphic--slate

  9. Rock Mugshots $400 Q • Coarse-grained crystalline rock composed of potash feldspar crystals in a light-colored aphanitic mass

  10. Rock Mugshots $400 A • Igneous—trachyte porphyry

  11. Rock Mugshots$500 Q • Recrystallized limestone containing some impurities

  12. Rock Mugshots$500 A • Metamorphic—serpentine marble

  13. This rock ison fire!$100 Q • Compare and contrast the formation of intrusive and extrusive igneous rocks.

  14. This rock is on fire! $100 A • Intrusive= magma hardens beneath Earth’s surface • Extrusive= lava hardens (above Earth’s surface)

  15. This rock is on fire! $200 Q A rock has a porphyritic texture. What can you conclude about the rock?

  16. This rock is on fire! $200 A Very different sized minerals minerals crystallize at different temperatures or at different rates

  17. This rock is on fire! $300 Q • Apply what you know about cooling rates to explain differences in crystal sizes.

  18. This rock is on fire! $300 A • Slow cooling rates large, well-formed crystals • Fast cooling rates small crystals that might or might not be well formed.

  19. This rock is on fire! $400 Q Is it possible for two different types of igneous rocks to have the same composition and the same texture? Explain.

  20. This rock is on fire! $400 A No, if two rocks have the same composition, then they are the intrusive and extrusive equivalents of one another. Thus, they cannot have the same textures. (ex: granite & rhyolite)

  21. This rock is on fire! $500 Q • Describe 3 of the 4 major compositional groups of igneous rocks

  22. This rock is on fire! $500 A • Granitic= mostly light-colored silicate minerals (feldspar & quartz) • Basaltic= mostly dark silicate minerals and plagioclase feldspar • Andesitic=mixture of both light and dark (granitic & basaltic) • Ultramafic= all dark silicate minerals (olivine & pyroxene)

  23. Under pressure $100 Q • Which term best describes this rock’s texture? WHY?! • Crystalline • Nonfoliated • Foliated • Clastic

  24. Under pressure $100 A • FOLIATED (layers)

  25. Under pressure $200 Q • Summarize what causes foliated metamorphic textures to form.

  26. Under pressure $200 A • High pressure causes minerals with flat or linear crystals to grow with a preferred or unidirectional orientation.

  27. Under pressure $300 Q • Explain how temperature increases can cause metamorphism.

  28. Under pressure $300 A • Increases in temperature cause reorganization of the atoms in the elements that make up the minerals new minerals form or mineral crystals increase in size

  29. Under pressure $400 Q • Distinguish between regional and contact metamorphism.

  30. Under pressure $400 A • Contact=when igneous intrusion comes in contact with solid rock and affects small area • Regional=high temp. pressure affects large areas of Earth’s crust

  31. Under pressure $500 Q • In what ways do metamorphic rocks differ from the sedimentary and igneous rocks from which they form? List & explain at least 2 reasons.

  32. Under pressure $500 A • Foliated/nonfoliated • Contain metamorphic minerals (mica, garnet, talc, etc.) that are stable under different conditions that other minerals (certain temps. & pressures)

  33. BreakingBad $100 Q • Differentiate between clastic and chemical sedimentary rocks.

  34. Breaking Bad $100 A • Clastic=bits of weathered material • Chemical=formed from dissolved minerals precipitated from H2O solutions

  35. Breaking Bad $200 Q • Explain why you would find the oldest fossils at the bottom of a cliff and the youngest fossils at the top of a cliff.

  36. Breaking Bad $200 A • Superposition layering of new material due to deposition and sedimentation/cementation

  37. Breaking Bad $300 Q • Analyze the environmental conditions to explain why most chemical sedimentary rocks form mainly in areas that have high evaporation rates.

  38. Breaking Bad $300 A • Evaporation—continuously removes freshwater from the body of water • Helps to maintain high concentrations of minerals in the remaining water • minerals precipitate out to form chemical sed. rock!

  39. Breaking Bad $400 Q • Identify the types of environments in which fine-grained sedimentary rocks form. siltstone

  40. Breaking Bad $400 A • Slow moving water (ponds, swamps, deep ocean) • Sediments settle to the bottom and accumulate in thin horizontal layers

  41. Breaking Bad $500 Q • Determine whether you are walking upstream or downstream along a dry mountain stream if you notice that the shape of the sediment is getting more angular as you continue walking. Explain.

  42. Breaking Bad $500 A • Because sediment becomes more rounded as it travels away from its source, you can determine that you are walking upstream, toward the source of sediments.

  43. Mixed Bag or Minerals $100 Q Name this character: Feldspar is considered a _____ because it has a characteristic chemical composition and a definite internal structure.

  44. Mixed Bag or Minerals $100 A Thumper from Bambi Mineral

  45. Mixed Bag or Minerals $200 Q Mary’s father has 5 daughters – Nana, Nene, Nini, Nono. What is the fifth daughters name? What characteristic is used for classifying minerals into individual groups?

  46. Mixed Bag or Minerals $200 A Mary Chemical composition

  47. Mixed Bag or Minerals $300 Q Who scored a record 10 hat tricks in an NHL season? Illustrate a silica tetrahedron.

  48. Mixed Bag or Minerals $300 A Wayne Gretzky

  49. Mixed Bag or Minerals $400 Q Cats are unable to detect what taste? Calcite(CaCO3) is the dominant mineral in the rock limestone. In which mineral group does it belong?

  50. Mixed Bag or Minerals $400 A Sweet Carbonates (CaCO3)
