Erosion and Transportation Processes

• Hydraulic action


  Air becomes trapped in joints and cracks in the cliff face. When a wave breaks, the trapped air is compressed, which weakens the cliff, and causes erosion
• Abrasion


  Bits of rock and sand in waves are flung against the cliff face. Overtime, they grind down the cliff surfaces like sandpaper.
• Attrition


  Waves smashed the rocks and pebbles on the shore into each other, and they break becoming smaller and smoother
• Corrasion


  Weak acids contained in seawater will dissolve some types of rock, such as chalk or limestone
• Solution


  Minerals are dissolved in water
• Suspension


  Small particles are carried in the water, for example, silts, and clays
• Saltation


  Rocks are bounced along the seabed
• Traction


  Pebbles and largest sediment are rolled along the seabed
