QUIZ #4 :

13. (+5) During the Cenozoic, there were quite significant extrusive igneous events in the American West. There were none east of the Mississippi River. Explain the situation in both cases.

14. (+5) Why are there such fossiliferous continental deposits of Cenozoic age east of the Rockies and west of the Mississippi River in the U.S., and nothing of the sort in the upper mid-west or eastern U.S.?

15. (+5) Once plants appeared on land, did the plants change the atmosphere, or does the content of the atmosphere dictate plant evolution? If you think about it, is not the sequence of seed ferns - gymnosperms - angiosperms quite some package of change through time? What could have influenced such changes?

16. (+5) Where in the eastern part of the U.S. would you find sedimnetry rocks (though poorly lithified) of Cenozoic age? How did they originate? Would you expect to find land-based fossils or marine fossils in these deposits?
