Coastal Landforms

Coastal Landforms. Landforms created by erosion. Landforms of erosion. Wave-cut platform. Cliffs and wave-cut platform. Caves, arches, stacks and stumps. Caves, arches, stacks and stamps. When caves are formed on both sides of a headland, their back join and an arch is formed.

Presentation Transcript

  1. Coastal Landforms

  2. Landforms created by erosion

  3. Landforms of erosion

  4. Wave-cut platform

  5. Cliffs and wave-cut platform

  6. Caves, arches, stacks and stumps

  7. Caves, arches, stacks and stamps

  8. When caves are formed on both sides of a headland, their back join and an arch is formed.

  9. The sea continues to erode the bottom of the arch. Weathering also take place on the bare rock faces. As the sea undercuts the bottom of the arch, a wave-cut notch will form.

  10. The arch will collapse, in time, as it is pulled down by the pressure of its own weight and gravity. This leaves behind a column of rock not attached to the headland, called a stack.

  11. Continued wave erosion and weathering will lead to the formation of a stump that is only visible at low tide.

  12. HomeworkDraw annotated diagrams to explain the formation of landforms of erosionTitle before each diagram (in dark pencil) Annotations around the diagrams. Not below!

  13. Movement of sediment along the coast

  14. Longshore drift

  15. Impacts of longshore drift

  16. What is an estuary?

  17. What is dredging?to remove material from the bottom of the sea or a river.

  18. Landforms of deposition(constructive waves)

  19. Beaches

  20. Sandy beach

  21. Durdle Door : a shingle beach separated by the famous “door” Dorset UK

  22. Seaside resorts often build groynes to keep beaches in place and to reduce the effects of longshore drift

  23. On the land side, silt and alluvium are deposited and salt marshes form.

  24. Bars

  25. Slapton Ley Bar in Devon

  26. Example in Cyprus: Larnaca Salt lake is a lagoon with the bar on the East
