Question

5. Whe re was the landmass that now forms southern Europe toward the end of the Devonian Period . How did the landmass that now forms the British Isles come into being? low do reefs of middle Paleozoic age illustrate ecological succession? 8. Re efs are commonly porous structures that serve as traps for petroleum. If you wanted to drill for oil in De- vonian reefs, what geographic regions would seem most promisin?g 9. What caused large quantities of sediment to ac- cumulate in the south-central part of Euramerica during the Devonian Period? 10. What evidence is there of a decline in the concen- tration of atmospheric carbon dioxide during Devonian time? (Hint: Refer to Figure 10-11 and Earth System Shift 14-2.) 11. Land areas changed dramatically in the course of middle Paleozoic time. Using the Visual Overview on pages 330-331 and what you have learned in this chapter describe how continental surfaces changed during Silurian and Devonian time with respect to their distribution on Earth, their topography, and their colonization by terres- trial life.

Explanation / Answer

5- A minor supercontinent named Euramerica was created in the devonian period which was near the equator along with southern Europe.

6- British Isles are actually the group of islands including Great Britain that formed the northern segment of the avalonia microcontinent and got attached to Northern Ireland and Scotland during the acadian orogeny process.

7- Platy and hemispherical tabulates and colonial rugose corals formed the early forms creating a low mount as the time passed and the mound grew up towards the sea surface, stromatoporoids and algae and encrusted the sea wall side. Fossil preserved in reef rock reveals that a wide variety of invertebrates like brachiopodes, snails, bryozones, crinoids and bivalve molluscs lived on the mature reef.

8- Reefs were more abundant in the great lakes region and near the western continental margin of north America so this seems the most promising place to look for oil.
