Answer to Question 1

ANS: A
Although sediments do come from rivers and accumulate at natural dams, most of the sediment on the
continental shelf comes from erosion of the continent itself. Information can be found in the section
Continental Margins May Be Active or Passive.

Answer to Question 2

ANS: B
