Answer to Question 1

ANS: F
There are three divisions of the continental margin: the continental shelf, continental slope, and the
continental rise. The continental rise is a layer of sediment that blends the continental margin into the
deep ocean. Information can be found in the section Continental Margins May Be Active or Passive.

Answer to Question 2

ANS: T
Trenches and island arcs are among the most geologically active formations on Earth. These are

Topography of Deep-Ocean Basins Differs from That of the Continental Margins.
