Spit Formation

Longshore drift moves sediment along coastline in zig-zag pattern

Once the power of the wave becomes too weak to transport the sediment, it deposits the sediment

Over time, the sediment builds up and forms a ridge of sand (a spit)

If the prevailing wind changes direction, the sediment will be deposited parallel to the direction of the wind

Once the spit curves due to a change in wind direction, it is called a cusped or hooked spit

E.g Spurn Head, Yorkshire
