  3. Coasts • Processes that affect the shoreline • Geological work • Erosion • Transportation • Deposition Energy source = wind waves

  4. Coasts • Beach – region affected by wave energy

  5. Coasts • Beach – region affected by wave energy

  6. Coasts • Beach – rivers and cliffs are sources of sand

  7. Coasts • Onshore/offshore sand movement “summer” beach low energy waves “winter” beach high energy waves

  8. Coasts • Longshore sand movement “summer” beach low energy waves “winter” beach high energy waves
