1. The geologic time scale is, starting with the youngest and ending with the oldest: A. Cenozoic, Paleozoic, Mesozoic,  Precambrian. B. Paleozoic, Mesozoic, Cenozoic,  Precambrian. C. Cenozoic, Precambrian, Paleozoic,  Mesozoic. D. Cenozoic, Mesozoic, Paleozoic,  Precambrian. E. Mesozoic, Cenozoic, Paleozoic,  Precambrian. You could probably reason this out if you remember some Greek roots, or else just memorize it—Cenozoic is  youngest, then Mesozoic, Paleozoic, and Precambrian. Points Earned: 0/1 Correct Answer: D Your Response: A 2. The “Law” of Faunal Succession: A. Requires that evolution occurred. B. Was developed by theoretical biologists to  explain evolution. C. Was passed in Congress to dictate equal  teaching of different theories of origins. D. Was developed by an engineering geologist  to aid in construction projects. E. Requires that evolution was a catastrophic  process.

In the late 1600s in England, William Smith discovered that putting the rocks in time order put the fossils in time  order, allowing him to use the fossils as a shortcut in understanding the rocks. We will see soon that faunal  succession is consistent with evolution but does not require it, does not require but might allow catastrophism,  and informed but was not developed by theoretical biologists. Faunal succession was known before Congress  was founded.  Points Earned: 0/1 Correct Answer: D Your Response: B 3. The Paleozoic: A. Is “old life”, the age of  algae. B. Is “new life”, the age of  dinosaurs. C. Is “new life”, the age of  mammals. D. Is “old life”, the age of  shellfish. E. Is “middle life”, the age  of dinosaurs. Paleo goes with Past, and is old life. The Paleozoic started with the “fast” (over a few million years) emergence  of many creatures with shells, which greatly increased the richness of the fossil record because shells are  preserved so well. Points Earned: 1/1 Correct Answer: D Your Response: D 4. An unconformity is:

A. An igneous rock intrusion cutting a sedimentary rock,  showing that the igneous rock is younger than the  sedimentary rock. B. The principle that younger sedimentary rocks normally  occur on top of older rocks, unless they are turned  upside-down by mountain building. C. A time gap in a sequence of sedimentary rocks caused  by a period of erosion or nondeposition. D. The principle that younger fossils look more like living  types than do older fossils. E.
