Answer 13

The Paleozoic, Mesozoic, and Cenozoic Eras
SECTION 23.1 The Paleozoic Era
In your textbook, read about the continental setting of the early Paleozoic.
For each statement below, write true or false.

True 1. Paleogeography is the ancient geographic setting of an area.
False 2. The ancient North American continent of Laurasia was once surrounded by ocean.
True 3. Laurasia was surrounded by passive margins throughout the Cambrian Period.
False 4. Carbonate sediments tend to accumulate in deep water as the calcium carbonate shells of organisms fall to the seafloor.
False 5. Evaporite minerals form in deep water environments, far from shore.
True 6. Oil deposits overlain by evaporate deposits rarely leak to the surface.
True 7. The Appalachian Mountains formed during the Alleghenian Orogeny.
False 8. The largest mass extinction occurred at the end of the Ordovician Period.

In your textbook, read about changes in sea level during the early Paleozoic.
Use each of the terms below to complete the following statements.
carbonate-rich sediment
clay-rich sediment
limestone-shale-sandstone
regression
transgression
vertical succession
shoreline


9. A transgression occurs when sea level rises and the _________________ moves
farther inland.
10. _________________ is found deposited in water slightly deeper than the beach.
11. A _________________ causes deep-water deposits to overlie shallow-water deposits.
12. A _________________ occurs when sea level falls resulting in the shoreline moving seaward.
13. A stacked sequence of _________________ deposits is evidence of a regression.
14. Sediments that are deposited adjacent to each other also end up in _________________ when sea level changes.

In your textbook, read about early Paleozoic life.
Circle the letter of the choice that best answers the question.
