2. Where do most volcanoes on earth occur?

3. • Along tectonic plate boundaries

4. How does silica affect the viscosity of magma?

5. • More silica means high viscosity…which
means it is thick and doesn’t flow as easily

6. Which is younger, layer D or intrusion A?

7. • Intrusion A

8. Based on the seismic readings, which location is
nearest to the epicenter of the earthquake?

9. • The seismic station in Oregon is closest

10. What are the three types of sedimentary rock?

11. • Chemical
• Clastic
• Organic

12. What is the relationship between the size of
mineral crystals and the cooling rate of an
igneous rock?

13. • The slower the magma cools, the larger the
crystals

14. Using the graph, how many years will it take
50% of the C-14 to decay?

15. • 5730x2=11,460 years

16. Why is C-14 not used to date objects over 50000
years old?

17. • After 50000 years, there is not enough parent
material left to measure

18. The preserved remains of living organisms are
called?

19. • Fossils

20. What is the S-P interval of the seismogram?

21. • About 40 seconds (39ish)

22. If the S-P interval of
an earthquake is 47
seconds, how far
away was the
earthquake?

23. • 460 km

24. The order of seismic waves

25. • Primary (P)
• Secondary (S)
• Surface (L)

26. The oldest rock layer in the picture

27. • Layer I

28. The youngest rock layer in the picture

29. • Layer H (intrusion)

30. What is the difference between magma and
lava?

31. • Magma is molten rock underground, while
lava is the same thing on the surface.

32. Predict the silica content of magma with low
viscosity.

33. • Low viscosity means that the lava would flow
easily. This would mean a low silica content.

34. How are the rocks
forming at A
different from
rocks forming at
B?

35. • Rocks at A are intrusive, they cool slowly from
magma and would have larger mineral crystals
• Rocks at B are extrusive, they cool quickly
from lava and have smaller mineral crystals

36. Most earthquake hazards are on the West coast.
Why do you thing there is an elevated
earthquake risk here?

37. • There must be an active fault in the middle of
the continent

38. Fossils that are used to pinpoint ranges of time
within rock layers and help scientists to correlate
layers of rock are known as _______

39. • Index Fossils

40. Which organism would make the best index
fossil?

41. • Organism A would be best…it is only found in
1 layer and is abundant and occurs over a
large geographic area

42. The process of sequencing rock layers from
oldest to youngest based on their position.

43. • Relative dating

44. The type of volcano with steep sides and
alternating layers of lava and ash. It has the
most violent eruptions

45. • Composite or Stratovolcano

46. This law/principle states that in undisturbed
rock layers, each layer is older than the one
above it

47. • Principle of Superposition

48. Portions of rock layers that are missing or
altered due to erosion and other disturbances
are called _______________

49. • Unconformities

50. The type of volcano made of lava flows with
gentle sloping sides

51. • Shield volcano

52. Which environment would be least likely to provide
conditions for fossil formation?
A dried up lava flow
A dried up river bed
A dried up tar pit
A block of glacial ice

53. • A dried up lava flow

54. The intersection of the 3 circles indicate the
_____ of an earthquake

55. • epicenter

56. If you are at a seismic station and there are no Swaves detected from an earthquake, what can
you assume about the earthquake’s location in
relation to where you are?

57. • The earthquake was on the other side of the
Earth. The S-waves were stopped by the liquid
outer core.

58. Based on the graphic, a Plinian eruption reads
what on the VEI scale?

59. • VEI = 8

60. If Mt. Holly erupts with a VEI of 5, how long would
you expect there to be between the next eruption?

61. • 100’s of years

62. Name one way a large volcanic eruption could
affect one of the spheres

63. • Geosphere – creates new land, ash adds nutrients
to soil
• Hydrosphere – ash gets into waterways and
sediment builds up, gases get incorporated into
water cycle causing acid rain
• Atmosphere – gases and ash are transported long
distances by wind, temperatures may cool as
some gases cause the deflection of sunlight
• Biosphere – living things are destroyed by many
of the hazards, food chains are disrupted

64. Which type of boundary is responsible for the
volcanoes in Hawaii?

65. • Hawaii is not on a boundary but is the result
of a hot spot.

66. What was most likely the cause of the events in
this picture?

67. • This tsunami was most likely caused by a large
earthquake under water

68. What type of metamorphic rock has mineral
bands aligned in layers as pictured below?

69. • foliated

70. Which type of
metamorphic rock
requires the most
heat and pressure to
form?

71. • Gneiss

72. Using the half life of radioactive elements
enables you to determine the ______ age of a
rock or fossil.

73. • absolute
