Answer to Question 1

ANS: C
Each type of delta is dominated by a distinguishing characteristic. River-dominant deltas are shaped
like a bird's foot from the flow of the river. Tide dominated deltas create islands parallel to the river
flow. Wave-dominated deltas tend to be small and have smooth shorelines with sand dunes.

Answer to Question 2

ANS: D
Erosional coasts also must contend with the alternate freezing and thawing or water within rocks,
glacial activity, and rainfall. Both land and marine erosion processes modify these coastlines.
