Deposition at the coast

    Cards (2)

    • Spit
      1. Sediment is carried by longshore-drift
      2. When there is a change in the shape of the coastline, deposition occurs. A long thin ridge of material is deposited.
      3. A hooked end can form if there is a change in wind direction
      4. Waves cannot get past a spit, therefore the water behind a spit is very sheltered
    • Bars
      Sometimes a spit can form a bar, this joins two headlands together. They trap shallow lakes behind the bar, these are known as lagoons
