  • 1. Geography Coastal landforms and processes
  • 2. What type of waves are these? Geography Spilling Breaker Weak Backwash Powerful Swash © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools
  • 3. Constructive Waves Geography Spilling Breaker Weak Backwash Powerful Swash © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools

  • 5. Destructive waves Geography Crashing breaker sh ul Backwa Powerf © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools sh Weak swa
  • 6. Geography Coastal erosion Can you mention the four different types of coastal erosion? • • • • © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools
  • 7. Geography Coastal erosion • • • • Attrition Corrasion Corrosion Hydraulic Action Would you be able to explain them? © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools
  • 8. Cliff line Geography Joints and beds allow waves to attack the cliff more easily HIGH TIDE LEVEL Waves can use rocks to erode the cliff Wave cut platform © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools Wave cut notch
  • 9. Geography The force of the waves pushes air into cracks in the rock The compressed air exerts enormous pressure at the tip of the crack. As the water falls back the air pressure is released and rock is pulled out from the crack further enlarging the hole.

  • 28. Geography Revetments and steel piling Gabions of stones,. They are retained behind timber works, a concrete esplanade and steel piling! Revetments, steel piling, rip rap and wooden retaining posts Rip rap and recurved sea walls A stepped sea wall, and concrete/stone groynes A stone groyne & rip rap protects the cliff in the foreground. a small beach has built up to the north of the groyne. © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools
  • 29. Geography A beach protects the coast from the force of the waves. Groynes stop the beach material moving along the beach © Tom Abbott, Biddulph High School and made available through www.sln.org.uk/geography and only for non commercial use in schools
