The shallow, protected bodies of water behind baymouth bars and barrier islands are lagoons. The waves impart a shear stress (force per unit area) to the shorezone and cause longshore transport that moves sediment along the coast. D. Barrier islands may be associated with a general rise in sea level and are separated from the mainland by a lagoon Even though the percentage is low, the volume is large, so melting the glaciers away will raise sea level and flood the coastlines of the world.

Again we return to water as an agent of transport. Glosario de Geologia | PDF | Absorption Spectroscopy | Glacier In areas where there is sufficient sediment being transported, and there are near-shore islands, a tombolo may form (Figure 17.20).
