layer?

B.
zone of turbulent mixing
C.
zone of very dense, cool water
D.
zone of low-salinity, dense water
Question 2
Which statement best describes the difference between ocean
surface currents and deep ocean currents?
A. Surface currents are cooler than deep currents
because of the influence of wind.
B.
Surface currents are driven by wind; deep
currents are driven by density differences.
C.
Surface currents are slow-moving; deep currents
are fast-moving.
D.
Surface currents are denser than deep currents.
Question 3
Flat areas that
occupy the deepest parts of the ocean floor are called the
A.
abyssal plains
B.
guyots
C.
oceanic trenches
D.
continental shelves
Question 4
Where does most of the deep ocean water come from?
A. sinks from the North Atlantic
B. input from rivers and streams on the
continents
C. upwelling from the Indian and
Pacific Oceans
D. melting of polar ice sheets
Question 5
What effect might
the introduction of more freshwater into the North Atlantic have on global
ocean circulation?
A.
speed it up
B.
stop it completely
C.
block it and slow it down
D.
make it flow in the opposite direction
Question 6
What happens
during El Nino years when coastal upwelling off the coast of South America is
disrupted?
A. plankton populations flourish and fishing is
very productive
B.
plankton populations stay fixed but fish
populations boom, creating imbalance in the ecosystem
C.
plankton populations die off and fishers are put
out of work
Question 7
From which of the
following do clouds form?
A.
moisture evaporated from Earth
B.
moisture from winds
C.
water droplets from the upper atmosphere
D.
air pollution
Question 8
