Factors affecting rates of erosion
  1. Wave power
    1. Wind speed/prevailing direction
      1. Defences - more defences = less erosion
        1. Rock type
          1. Hard/soft
            1. Limestone vulnerable to erosion
          2. Land use
            1. More buildings = more pressure
              1. More runoff = slumping
              2. Fetch
                1. longer distance = more powerful wave
                2. Weather conditions
                  1. PH of sea
                    1. More acidic = more erosion
                      1. climate change = increased CO2 = ocean acidification
                      2. Amount of sediment
                        1. Atrrition/abrasion
                        2. Wave type
                          1. Constructive/destructive
