Answer to Question 1

ANS: B
The Ekman spiral has to do with layers of water responding to the initial wind friction at the ocean's
surface. Each layer of water under the initial top layer moves slightly towards the right in the Northern
Hemisphere. Each layer moves slower than the layer above it. Information can be found in the section
Surface Currents Are Driven by the Winds.



Answer to Question 2

ANS: C
Thermohaline circulation is the movement of water due to density differences. The whole ocean is
involved in this slow circulation. Information can be found in the section Thermohaline Circulation
Affects All the Ocean's Water.
