2B.4B: Wave Erosion Processes

• Hydraulic action

  Waves breaking at the foot of the cliff force air in cracks to be compressed
• Attrition

  Rocks carried in water hit into each other to become rounder, smaller and smoother
• Corrosion

  Water in waves dissolves rock minerals
• Abrasion

  Rocks carried by the sea are thrown against a cliff face causing material to be broken off and carried away
