Question

Barrier islands:

a. Are eroded by strong wave action on their seaward side, thus moving them landward.
b. Are long, low narrow, coast-parallel, sandy islands typically less than a meter or two above sea level.

Answer 1

b. Are long, low narrow, coast-parallel, sandy islands typically less than a meter or two above sea level.

Step-by-step explanation:

• The barrier islands are those islands that are formed by the coastal erosion and are a type of a dune system that has a flat or lump area of sand and is formed by the waves and the tidal actions and are subject to change during the storms and other actions.

• The barriers islands are formed by the several components parts as the foreshore and the backshore and the dunes and the tidal flats and their process of formation starts with a certain width like the outwash and the washover deposits and is a process that continues for about 150 years. And consists of the major theories of the formation related to the offshore bar, the spit accretion, and the submergence.
