  2. He was the name of the explorer who mapped out he Grand Canyon

  3. Who was John Wesley Powell?

  4. These are always younger than the rock layers around them.

  5. Extrusion, intrusion, and faults.

  6. These are the process responsible for making the Grand Canyon

  7. Weathering , erosion, plate tectonics, converging plates, ice, and volcanoes

  8. This is younger than the other layers.

  9. The Fault labeled Y.

  10. This was a high, flat, land formed west of the Rocky Mountains

  11. The Colorado Plateau

  12. This type of rock is formed from sediments

  13. Sedimentary Rocks

  14. The rock that responds to acid by bubbling because it has calcite in it

  15. What is Limestone?

  16. It is another name for rock layers

  17. What is strata?

  18. Denoted rough rapids on the Colorado River

  19. What is rough, rigid, and harder rocks?

  20. Rocks made from hardened lava

  21. What is igneous rock?

  22. The remains or imprints of once live organisms

  23. What are fossils?

  24. The type of fossil that is formed by minerals absorbing into the hard parts of the organism and turning it into rock

  25. What are petrified fossils?

  26. Organisms that have been covered by tree resin and the resin hardens overtime fossilizing them.

  27. What are fossils in amber?

  28. Fossils that are widely distributed and occurred for only short periods of time.

  29. What are index fossils?

  30. Hollow impression in sediment that is the shape of an organism

  31. What are molds?

  32. Copy or replica of the shape of an organism

  33. What are casts?

  34. Fossils that are evidence that the organism was there, but not a part of the organism.

  35. What are Trace Fossils?

  36. These include bone, shells, teeth, and woody stems.

  37. What are the parts of the organism that form fossils?

  38. The 3 main things fossils tell scientists

  39. What kind of organisms lived I the past. • How the organisms have changed. • How the environment has changed

  40. A foot print, animal burrows, and caprolites

  41. What are examples of Trace Fossils?

  42. This is the age of rocks when comparing rock layers

  43. What is relative age?

  44. States that rock layers on the bottom are always older that layers above them.

  45. What is the Law of Superposition?

  46. The exact number of years since the rock has been formed.

  47. What is absolute age?

  48. Why index fossil are so important to us.

  49. They tell the relative age of rock layers

  50. Characteristics of an index fossil.
