Problem 2
If the North Atlantic Drift were to cease, how might the climate of Western Europe change?
Problem 3
During a visit to the beach, you and a friend get in a rubber raft and paddle out into deep water beyond the surf zone. Tiring, you stop and take a rest. Describe the movement of the raft during your rest. How does this movement differ, if at all, from what you would have experienced if you had stopped paddling while in the surf zone?
Problem 6
You and a friend set up an umbrella and chairs at a beach. Your friend then goes into the surf zone to play Frisbee with another person. Several minutes later, your friend looks back toward the beach and is surprised to see that she is no longer near where the umbrella and chairs are set up. Although she is still in the surf zone, she is 30 yards away from where she started. How would you explain to your friend why she moved along the shore?
Problem 8
If wastage (melting and calving) of the Greenland Ice Sheet were to dramatically increase, how would the salinity of the adjacent North Atlantic be affected? How might this influence thermohaline circulation?
Problem 9
The force of gravity plays a critical role in creating ocean tides. The more massive an object, the stronger its gravitational pull. Explain why the Sun's influence is much less than that of the Moon, even though the Sun is much more massive than the Moon.
