Barrier islands are quite rare along the Gulf of Mexicocoastline. When did the mouth bar form in the Wax Lake Delta? C) Sand is deposited from longshore currents. In areas where there is sufficient sediment being transported, and there are near-shore islands, a tombolo may form (Figure 17.20). Along which type of coastline are large estuaries more common? A. Elevated, wave-cut terraces The beaches get longer. Groins are constructed perpendicular to the beach; they aredesigned to trap sand that might otherwise keep moving along the beach. If the supply is not interrupted, and the spit is not breached by the sea (or, if across an estuary, the river), the spit may become a bar, with both ends joined to land, and form a lagoon behind the bar. How are spits, hooks, and baymouth bars formed? Baymouth bars form across bays where sea stacks stand on both sides of the entrance.

A. slightly clayey sand D. The main channel is divided into several tributaries, carrying sediment progressively farther out into the ocean at base level. A spit, which forms where a shoreline changes direction, is protected from wave action. A bar develops by the process of Longshore drift,which occurs due to waves meeting at the beach at an angle and backwashing perpendicular to the shore, moving sediment down the beach on a zigzag pattern.

Baymouth bar: If the spit continues to develop, it may completely enclose the embayment, forming a baymouth bar. Most bays have streams flowing into them, and since this water has to get out, it is rare that a baymouth bar will completely close the entrance to a bay. A baymouth bar is a manmade feature designed to stopincoming storm waves before they impact on the beach. What process describes incoming waves slowing down and rotating until they are parallel to the shoreline? A. Arete A spit may be considered a special form of a shoal.
