Answer to Question 1

ANS: D
Transform faults are fractures along which lithospheric plates move horizontally. Transform faults are
the active part of fracture zones and move in the same direction. 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: C
The multibeam echo system was more reliable and gave better resolution than single beam systems.
Unfortunately, there are fewer than 200 vessels equipped with the multibeam system. It would be
impossible to map the entire ocean in a reasonable amount of time. Information can be found in the
section Ocean Floor Is Mapped by Bathymetry
