How does longshore drift create a spit
A 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 … See more Where the direction of the shore inland re-enters, or changes direction, for example at a headland, the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This is … See more Since prehistory humans have chosen certain spit formations as sites for human habitation.
