  • Erosional Landforms
    • Wave cut notch
      • Grove at the bottom of the cliff
      • Caused by erosion of waves usually in low tide
      • Southern Downs
    • Blowholes
      • A cave will be formed and grow futher inland and upwards into a tube. This tube will reach the cliff top causing water to be pushed out. The higher the energy of the pushed out waves, the more water pushed out
      • A tube in a cave through which water can be pushed out
      • Stair Hole, Dorset
    • Wave cut platform
      • Flat surface at the base of the cliff
      • Cliff collapses and the waves take the sediment into the sea
      • Southern Downs
    • Geo
      • Calder's geo, Shetland Islands
      • Created by wave driven erosion of  cliffs along faults and planes, usually hydraulic action
      • An inlet, a gullley or deep cleft in the face of a cliff
    • Headland
      • The sea attacks a section of the coast with alternating bands of hard and soft rock. Bands of soft rock erode quicker that those of more resistant rock and so leaves a section of land jutting out into the sea
      • A narrow piece of land that protects from a coastline into the sea
      • Durlston Head, Dorset
    • Coves
      • Waves seek faults in the hard concordant coastline where it erodes through to the softer rock behind. The erosion happens faster in the soft rock creating a circular shape with a narrow enterance in the hard rock. The waves are then refracted in the cove helping it maintain its circular shape.
      • Lulworth cove, Dorest and McWay cove, California
      • A sheltered bay or coastal inlet
    • Arches
      • A hollow within a headland
      • Green bridge, Wales and Durdle Door, Dorset
      • An arch is formed from a widened cave which continues all the way through the headland
    • Caves
      • Widened faults in a cliff face
      • Fingal's cave, Staffa, Scotland
      • The faults are widened by wave erosion and become wide enough for people to go inside, creating a cave
    • Stacks
      • A steep and often vertical column isolated, by erosion, ffrom the headland
      • Formed when weathering attacks the top of an arch, eroding it and leaving a vertical column
      • Old Harry Rock, Dorset
    • Stump
      • Formed by the undercutting of a stack
      • A shorter version of a stack
      • Old Harry's Wife, Dorset
