b) It would get much colder and would snow instead of rain.
c) It is impossible to know.

9) The Gulf Stream flows up the eastern U.S., but it has a much greater effect on the
climate of Northern Europe. Why?
a) The prevailing winds at those latitudes are from east to west.
b) When it gets to Eurasia, it meets the North Sea and mixes with that colder water.
c) The prevailing winds at those latitudes are from west to east.
d) None of these.
2 10) London gets a lot of rain because
a) The Gulf Stream warms the air above it so that it can hold more moisture, which it drops
when it cools off over the British Isles.
b) The Gulf Stream mixes with the Labrador Current, which causes warm and cold air to
