Key Info
  • Coastal landforms - blowholes and cliff slumping
  • Duration: 02:07
  • Blowholes are vertical faults which have been widened by wave attack. Headlands are made up of hard rock and bays formed where softer rock erodes away more quickly. Sub-aerial processes, such as rainfall, can also cause erosion. This often happens where layers of boulder clay, left behind by melting glaciers, become saturated and cause the cliff to slump.
