Answer to Question 1

ANS: D
Erosional coasts are so named because they remove materials through a variety of marine and
terrestrial processes. Depositional coasts are either steady or growing due to their sediment
accumulations. Information can be found in the section Coasts Are Shaped by Marine and Terrestrial
Processes.

Answer to Question 2

ANS: A
The particles that make up sand on the Pacific coast are dominated by quartz and feldspar. These
components are derived from granite rock. Information can be found in the section Characteristics of
U.S. Coasts
