1. Scientists that study forms of marine life that lived more than approximately 200 million years ago usually have to obtain fossils not from the sea floor, but from areas that were once undersea and been uplifted onto the continents. Why do you think this is?

2. The winter of 1984-85 was particularly cold in Europe. The northern part of the Black Sea, froze, which is rare in the normally mild climate. The Adriatic Sea, located east of the Black Sea, has just as cold of a winter but never froze. The Black Sea has an unusually low salinity of about 18ppt. What would you say about the salinity of the Adriatic Sea?
