B. C. Greenland ____________ are coastal structures designed to keep tidal and harbor inlets from shifting location or filling with sand. Because the land is rising faster than sea level, stormdamage and erosion along emergent coastlines are relatively unimportant. C. Aquicludes 193. Farewell Spit in New Zealand, at 32km (20mi), in the north-west area of South Island, is believed to be caused by the strong prevailing winds and currents, bringing sand eroded from the Southern Alps of the South Island and depositing these into Golden Bay. A. Evidence of wave action (symmetrical ripples). For a passing wave, the depth below which the motion of water particles become negligible is equal to Neap tides are produced when the Moon is at right angles to the line connecting the Earth and Sun.

A. slightly clayey sand Figure 17.20 A depiction of a baymouth bar and a tombolo [SE] B. well-sorted, coarse gravel how are spits, hooks, and baymouth bars formed? It is a shoal that somewhat or totally closes admittance to a sound. Tombolo's are created through the process of longshore drift A tombolo is formed where the spit continues to grow until it reaches an island, forming a link with the mainland, just like bridges.

Water flows into the aquifer on one end and is trapped by aquitards above and below. 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. B. Kettle D. Even though the percentage is low, the volume is large. Sand is deposited from longshore currents.

Characteried by: Sun heats atmosphere causing weather, movement of air. 3 How are spits hooks and baymouth bars formed? 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. Tombolos are sometimes referred to as "tied islands", because it seems to tethered to the coast. This beach connects to the Isle of Portland, a 4-mile long, limestone island. 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.
