Answer to Problem 1TC

An erosional coast is a new coast where the removal of coastal material is the dominant process, whereas a depositional coast is normally older that grow or are steady coast because of their rate of sediment deposition or the coral activities.

Explanation of Solution

The coast is influenced by various factors; however, the most useful scheme to classify that is based upon the major occurrences such as erosion and deposition.

The erosional coasts are new coasts where the dominant processes involve the removal of coastal materials. Depositional coasts are stable or growing coasts due to their rate of sediment accretion or the action of living organisms (such as corals).

Examples of erosional coasts are the rocky shores of Maine as the rate of erosion exceeds the deposition rate there. The examples of the depositional coasts are sandy coastline from New Jersey to Florida because sediment deposits tend to guard the shore from new erosion.
