Resumo de Recurso

How waves erode
  1. Hydraulic action
    1. The sheer power/force of the waves pushes the water into cracks in the rock and compresses the air. Pressure will eventually cause the rock to break
    2. Abrasion/ Corrasion
      1. Waves contain material like pebble and shingle. It hurls them against a cliff faces and the material in the wave is used to break the cliff up.
      2. Corrosion
        1. Sea water reacts chemically with the rock and dissolves it
        2. Attrition
          1. This is when the rocks in the water knock against each other and become smaller, rounded and smoother
