Answer to Question 1

ANS: B
Barrier islands are narrow and exposed sand-bars. They are parallel to the shore, but separate from the
land. Information can be found in the section Larger-Scale Features Accumulate on Depositional
Coasts.

Answer to Question 2

ANS: C
There are three factors that heavily impact eustatic change. Global glaciations, the amount of seafloor
spreading, and temperature variations can cause long-term changes in sea level. Information can be
found in the section Coasts Are Shaped by Marine and Terrestrial Processes.
