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.
