Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. B. Convection through the atmosphere Additionally, its bottom "drags" causing it to spill forward or "break". B. Irregular shorelines Longshore sand transport and longshore currents depend onwaves impinging parallel to a shoreline. A) increased, longshore current velocities between the breakwater and the beach B) dissipation of storm wave energy on the seaward side of the breakwater C) increased sand deposition between the beach and the breakwater D) increased erosion of the beach on one side of the breakwater, A)increased, longshore current velocities between the breakwater and the beach, A natural sand bar or low, sand ridge that connects one island to another island or to the mainland is called a ________. tombolo Beaches are a common feature of a coastline. Necessary cookies are absolutely essential for the website to function properly. Which of the following statements concerning the Mississippi delta lands is not true? The New York-New Jersey Harbor Estuary, also known as the Hudson-Raritan Estuary, is in the northeastern states of New Jersey and New York on the East Coast of the United States.The system of waterways of the Port of New York and New Jersey forms one of the most intricate natural harbors in the world and one of the busiest ports of the United States. D. Aquitards, 57) Of the substrates listed below, which would have the largest capacity to naturally remove sewage pollutants? C. Drumlin As the waves move into shallower water, the angle between the wave crests and shoreline increases and the crests become perpendicular to the shoreline Thus, they most commonly occur across artificial bay and river entrances due to the loss of kinetic energy in the current after wave refraction. What makes a bay a spit or a baymouth bar? waves diverge in coves, minimizing impact and depositing beach sediment on the landward margin of the surf zone the turbulent sheet of water from collapsing breakers, called swash, moves up the slope of the beach. ________ are coastal structures designed to keep tidal inlets from shifting location or filling with sand. The Lockport Dolostone is a nonresistant rock unit, and the Niagara River can cut through it quickly. C.

These cookies will be stored in your browser only with your consent. Wave refraction can occur at the end of a spit, carrying sediment around the end to form a hook or recurved spit. The waves impart a shear stress (force per unit area) to the shorezone and cause longshore transport that moves sediment along the coast. This is a picture of a growing spit that crosses a bay in which it forms a baymouth. L = wave length The beach side of barrier islands is identical to the lagoon side in terms of overall appearance, types of sediments, and vegetation C. Horn A. Through this process material is constantly moved along the coastline. This process is called longshore drift. The hook always indicates the direction in which the longshore current is flowing towards. In a similar fashion, the Vistula Spit separates the Vistula Lagoon from the Gdask Bay off the coast of Poland. C) It has remained about the same. These bars usually consist of accumulated gravel and sand carried by the current of longshore drift and deposited at a less turbulent part of the current.

Tectonic shifts and sea level changes cause the long-term rise and fall of sea level relative to land. At this point only, we get net transport of water in wave direction. B. A 1.905-cm-diameter brass tube is used to condense steam on its outer surface at 10.13 kPa pressure.
