Clues

  • after rotational slide has occured. loose waethered debris accumilates. when sufficient material has built up, it will slide downslope towards the sea. (8)
  • also known as hydrolic action. impact of masses of water by wave shock and wave hammer. involves pressure release where air in cracks in rocks is compressed by breaking waves. well jointed/weak rocks are most susceptible to this. (9)
  • also known as solution weathering. sea and rain water containing carbon dioxide in solution react with calcium carbonate to dissolve soft sedimentary rocks such as limestone and chalk (9)
  • breaking waves throw rocks at shoreline creating a scouring effect. dependant on avalability of loose material, hardness of rock particles in relation to shoreline material, resistance of rocks on shoe and depth of water (8)
  • occurs in weaker rocks such as clay and has a distinctive curved slide plane. caused by wave erosion at base of cliff and heavy rain which loads slope and weakens clay (10, 5)
  • steep cliffed coastlines. detachment of rock occurs along joints. triggered by undercutting of cliff at base by wave action (8)
