Go to the website above and take the quiz. Write your answers on the questions below. Evaluate
your answers and make any corrections in a DIFFERENT color.
How did you get correct on the first try? __________________
1. Currents are water movements created by?
1. the wakes of large ocean-going vessels (ships).
2. friction between moving air (wind) and the
water's surface.
3. earthquakes.
4. none of the above
2. Surface currents:
1. are wind-driven.
2. are the only currents that most people see.
3. affect about 20% of the ocean's volume(total
water).
4. all of the above
3. Deep-ocean currents are:
1. non-existent
2. wind-driven
3. density-driven
4. circumpolar
4. Winds and ocean currents are ultimately
created by the:
1. equator
2. sun
3. moon
4. all of the above.
5. Winds and ocean circulation (currents) are
created as a result of:
1. Moon's orbit around Earth
2. satellites orbiting Earth.
3. unequal solar heating of the oceans and the
atmosphere.
4. 1 & 2
6. A "south wind":
1. blows out of the north to the south.
2. blows out of the south to the north.
7. A "northerly current":
1. flows to the north.
2. flows out of the north.
8. Once surface currents are set in motion,
they are affected by three other factors:
1. Coriolis effect, presence of coasts, &
horizontal pressure gradient
2. Gyres, eddies, & geostrophic flow
3. Hurricanes, earthquakes, & tsunamis
4. Ships, whales, & icebergs
9. Only one ocean current flows unimpeded
(without obstruction or barriers) around
Earth. It is the:
1. Gulf Stream Current
2. California Current
3. Antarctic Circumpolar Current
4. Aghulas Current
10. A deflection of ocean water--to the right
in the Northern Hemisphere and to the left in
the Southern Hemisphere--caused by Earth's
rotation is called:
1. The Coriolis effect
2. The Langmuir circulation
3. A gyre
4. Horizontal pressure gradient
11. Variations in the ocean's circulation can
lead to variations in the heat transport and
thus lead to variations in:
1. coastlines
2. shipping lanes
3. occurrence of tides
4. weather patterns
