Spits

Spits are also created by deposition. A spit is an extended stretch of beach material that projects out to sea and is joined to the mainland at one end.

Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. An example of a spit is Spurn Head, found along the Holderness coast in Humberside.

The development of Spurn Head

The Spurn Head spit
  1. Longshore drift moves material along the coastline.
  2. A spit forms when the material is deposited.
  3. Over time, the spit grows and develops a hook if wind direction changes further out.
  4. Waves cannot get past a spit, which creates a sheltered area where silt is deposited and mud flats or salt marshes form.
