  1. Geology Review • Please pick up your clicker!

  2. Please select a team based onyour favorite sport. • Hockey • Soccer • Basketball • Baseball • Football • Other

  3. Minerals

  4. 1. A mineral is defined as:A naturally occurring, ___, crystalline solid with a definite chemical composition. • element • organic • rock • molecule • inorganic

  5. 2. This mineral shows: • Cleavage • Crystal Form

  6. 3. The ability of a mineral to resist being scratched is known as: • Cleavage • Luster • Hardness • Streak • Crystal form

  7. Team Scores

  8. Rocks

  9. 4. This igneous rock is? • Intrusive • Extrusive

  10. 5. Most sedimentary rocks form from… • heat and pressure • melting • deposition • weathering

  11. 6. This rock shows folding and foliated bands of minerals indicating it is a(n): • Igneous rock • Metamorphic rock • Sedimentary rock

  12. 7. What type of rock is shown? • Sedimentary • Igneous • metamorphic

  13. 8. What process is occurring at X ? • Heat and Pressure • Melting • Weathering & Erosion

  14. 9. What process is occurring at Y ? • Heat and Pressure • Melting • Weathering & Erosion

  15. Team Scores

  16. Geologic Time

  17. 10. Nicolas Steno stated that in areas of undisturbed rocks, the oldest layer is found at the bottom and the youngest layer is found at the top. This is known as: • Law of Superposition • Uniformitarianism • Absolute time • Unconformity

  18. 11. Which is older, 3 or 1? • 1 is older • 3 is older • Not enough information to determine an answer.

  19. 12. Which is older, 3 or B? • 3 is older • B is older

  20. 13. “A” is a(n): • fault • rift • intrusion • unconformity

  21. 14. Radiometric dating is used to determine: • Absolute Time • Relative Time • Clean-up Time

  22. Team Scores

  23. Weathering & Erosion

  24. 15. The natural process by which earth materials are moved from their source and deposited elsewhere. • Weathering • Crystallization • Compression • Erosion

  25. 16. Which is not an example of mass movement? • Landslide • Mudslide • Avalanche • Creep • Tornado

  26. 17. Which of these would not increase the chance of a landslide? • Heavy precipitation. • Clearing vegetation off a slope. • An Earthquake. • A volcanic eruption • Solar Storms

  27. 18. Which of these glacial features is destructive? • Moraine • Drumlin • Esker • Striations

  28. 19. The rate of chemical weathering increases as precipitation increases and the temperature: • Increases • Decreases • Temperature has no effect on chemical weathering.

  29. 20. Which of these is a result of chemical weathering? • A change in the rocks mineral composition. • Roots breaking apart a rock. • Freezing water cracking a rock • An earthquake breaking apart a rock

  30. 21. The diagram shows a __ fault which is caused by __. • Normal, compression • Normal, tension • Reverse, compression • Reverse, tension • Not my fault

  31. 22. A landform that forms from sediments at the mouth of a river in a body of water is called: • Estuary • Delta • Levee • Tombolo • Sandbar • Spit

  32. Team Scores

  33. Plate Tectonics

  34. 23. If the Earth were to cool completely, which of the following would still continue? • Earthquakes • Volcanoes • Plate Movements • Convection currents inside the earth • Landslides • Subduction

  35. 24. Shield volcanoes are made of basalts with __ viscosity and therefore have __ eruptions. • High, violent • High, non-violent • Low, violent • Low, non-violent

  36. 25. True or FalseThe oldest rocks on earth are found on the continents, not on the ocean floors. • True • False

  37. 26. Most earthquakes and volcanoes are found: • in the center of the continents. • near large cities. • in mountain ranges. • along plate boundaries.

  38. Team Scores

  39. Fossils

  40. 27. Fossils used to define and identify geologic periods are know as: • Brachiopods • Index Fossils • Sedimentary Fossils • Crinoids • Coprolites

  41. 28. Almost all fossils are found in this type of rock. • Igneous • Metamorphic • Sedimentary

  42. 29. Alfred Wegener used fossil evidence to help support his theory of: • Sea-Floor Spreading • Continental Drift • Superposition • Cross cutting • Relativity

  43. 30. The Geology Unit has… • been really gneiss • made me a little sedimental. • no faults. • been earth shattering. • helped me not take things for granite. • made me loose my apatite. • has shaken me to my core.
