Year 8 Geography - Coastal Landscapes Summary

• Waves:

  • Constructive Waves: Build up beaches with a strong swash and longer wavelengths.

  • Destructive Waves: Cause erosion with stronger backwash and shorter wavelengths.

• Coastal Erosion:

  • Features like headlands, caves, and stacks formed through erosional processes.

  • Impacts of erosion on landforms and human activities.

• Coastal Deposition:

  • Features like spits and bars created through deposition processes.

Management Strategies

• Hard Engineering: Seawalls, groynes, and revetments.

• Soft Engineering: Beach nourishment and land use planning.

Key Terms

• Geomorphology: Study of landforms.

• Longshore Drift: Process of sediment transport along the coast.

• Rip Current: Strong current moving away from shore.

• Tsunami: Large ocean wave caused by underwater disturbances.
