How do longshore currents create spits
WebA spit or sandspit is a deposition bar or beach landform off coasts or lake shores. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs due to waves meeting the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. WebSpits are formed when longshore drift travels past a point (e.g. river mouth or re-entrant) where the dominant drift direction and shoreline do not veer in the same direction. [6] As well as dominant drift direction, spits are affected by the strength of wave-driven current, wave angle and the height of incoming waves. [7]

WebThe current theory is that barrier islands were formed about 18,000 years ago when the last Ice Age ended. As the glaciers melted and receded, the sea levels began to rise, and flooded areas behind the beach ridges at that time. WebLongshore currents are generated when a "train" of waves reach the coastline and release bursts of energy. The speed at which waves approach the shore depends on sea floor and shoreline features and the depth of …
WebJul 26, 2011 · Spits are formed as a result of littoral drifts traveling past the entrant point of a body of water, such as a river’s mouth or river’s entrant. Spits have two important features. On one end, the spit is attached to the land while the other end that is out into the sea resembles a hook shape due to varying wave directions.
