Answer to Question 1

ANS: T
The amount of Earth's surface below sea level could be due to the great density of ocean basins.
Information can be found in the section Ocean-Floor Topography Varies with Location



Answer to Question 2

ANS: F
Turbidity currents are actually propelled by gravity. The mass movement of sediments occurs when
turbulence mixes sediments into the water above a sloping bottom. The sediment then flows down the
slope, sometimes at great speeds due to the gravitational pull. Information can be found in the section
Continental Margins May Be Active or Passive.
