Spit Formation
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.
