4. When sand/sediment being carried in the waves is dropped/dumped (deposited)

5. Spits
A Spit is a long, narrow stretch of pebbles and sand which is attached to the land at one end with the other end extending into the sea

7. Longshore Drift occurs along a coastline
If the coastline ends/changes direction, the sea continues to deposit the transported material.
Over time, the material builds up to form a ridge of shingle and sand.
Changing wind directions may curve the end of the spit – spit shapes are always changing
A salt marsh will sometimes
form behind the spit where there is slow nearly stagnant water.
