Answer to Question 1

ANS: C
The mid-Atlantic ridge does not move in a straight line. Transform faults are fractures that move
horizontally, but faults in general are fractures in the lithosphere along which movement has occurred.
Information can be found in the section The Topography of Deep-Ocean Basins Differs from That of
the Continental Margins

Answer to Question 2

ANS: D
Deep-ocean currents are a major factor in the shaping of western boundary continental rises. These are
compressed against continental slopes due to the Coriolis Effect. Information can be found in the
section Continental Margins May Be Active or Passive.
