26. In review book.
27. an earthquake
28. (oldest) siltstone→ limestone → granite → shale→ basalt →
sandstone (youngest)
29. Permian
30. hornfels
31. The basalt is finer grained. The basalt has smaller crystals.
32. erosion
33. The sandstone is not metamorphosed (no contact
metamorphism).The basalt contains vesicles.The basalt is fine
grained.
34. sedimentary
35. Approximately 0° (near the equator). Accept answers within 20°N
and 20°S.
36. The actual fossil is 11.6 times as large. (Accept answers in the
range of 10–14 times as large.)
37. 60°North (5°), 90°West ( 5°).
38. Inference 1: The intrusion cuts through the shale. The intrusion
metamorphosed the
shale.
Inference 2: The sandstone rests on top of the shale.
Inference 3: There is an unconformity (erosion surface) below the
shale. Parts of the granite
and limestone appear to be missing.The bottom of shale shows no
contact metamorphism.
Inference 4: The limestone shows contact metamorphism
40. Ordovician
41. (1) deposition, (2) folding, (3) erosion (4) deposition, (5) erosion
42. 400 million years (5 million years, must include units of time [years])
43. Elliptocephala
44. Paleozoic
45. Appalachian (or Alleghanian) Orogeny
46. f or g
47. fish
48. Accept answers within the range of 444 to 488 million years.
