Spits are created by deposition. A spit is an extended piece of beach materail that projects out into the sea and is joined to the mainland at one end.
Spits are formed when the prevailing wind blows at an angle to the coastline, resulting in longshore drift.
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 in deposited and mud flats or salt marshes form
