A spit forms when the material is deposited. Over time, the spit grows and develops a hook if wind direction changes further out. Waves cannot get past a spit, which creates a sheltered area where silt is deposited and mud flats or salt marshes form.

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. 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.

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.
