Answer to Question 1

ANS: B
The residence time of most deep water is 200 to 300 years. This is less than in the Pacific (1,600
years), but is significantly more than surface water. Information can be found in the section
Thermohaline Circulation Affects All the Ocean's Water.



Answer to Question 2

ANS: A
Equatorial upwelling occurs worldwide in westward flowing equatorial surface currents. Upwelling is
crucial to marine organisms because it brings nutrients from below the pycnocline to the surface.
Information can be found in the section Wind Can Cause Vertical Movement of Ocean Water.
