Where a coastline turns and interrupts longshore drift, sand may be deposited in a fingerlike landform called a spit.

Longshore drift is the effect of longshore current because the water moves a certain way and causes the sand to take shape.
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.
Longshore current, sometimes called longshore drift, is an ocean current that flows parallel to and close to the shore. A link is provided to the Wikipedia article.
Shoreline is where land and a body of water meet and longshore is a movement of water parallel to and near to the shoreline.
Longshore current

Longshore drift moves material along the coastline. When the coastline curves, the material continues to be deposited in a straight line, unless the prevailing wind changes direction. As the material is deposited further out to sea, the waves cannot pass it, creating a sheltered area and salt marsh is formed.

It's a spit, A spit is made up of deposited material carried along by longshore drift.
Longshore current is the movement of water nearest the coast. Usually caused by tides. Longshore drift is the movement of beach or coastal material, by longshore drift. The action of waves loosen the material, which is then moved by the current and deposited further down tide. The action is greater during storms.
Shale beaches are formed from the deposition of sediment form nearby shale cliffs which are eroded. The shale can also be deposited at a beach due to longshore drift.
Spits are narrow, elongated ridges of sand or gravel that form due to the movement of sediment by longshore drift along a coastline. They typically extend from the shoreline into a body of water, often forming at the mouth of a bay or estuary where sediment is deposited by waves and currents. Over time, spits can grow and change shape as sediment is added to one end and eroded from the other.
