Answer to Question 1

ANS: D
The origin of most abyssal plain sediments is from the land and shallow waters. It is thought to be
transported by winds and turbidity currents. 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: B
The continental slope is the transition between the shelf and the seafloor. They are formed from
sediments that get transported along the build-out edge of the shelf. Information can be found in the
section Voyaging Combined with Science to Advance Ocean Studies.
