Test 2

• Coastal erosion creates certain landforms including headlands, bays, wave cut platforms, caves, arches and stacks
• Hard rock erodes more slowly than soft rock. Cliffs of hard rock just out into the sea,forming headlands. Softer rock will be eroded away forming a bay
• Caves are formed when water seeps through cracks in rocks and enlarges them by dissolving the softer rock around it. The roof collapses creating an archway which eventually becomes a cave.
• Stacks are created when waves erode the base of an arch until only the top remains
• Bays and headlands

  1. Bands of hard and soft rock are found at the coast
  2. Soft rock erodes quicker than hard rock
  3. Soft rock erodes via hydraulic action and abrasion forming bays
  4. Hard rock is resistant to erosion forming headlands
• 1. Waves attack a crack in the rock via hydraulic action and abrasion
  2. The crack gets bigger until eventually it forms a cave
  3. Continuous erosion at the back of the cave causes it to break through the headland forming an arch
  4. The base of the arch is eroded causing it to become weak. As a result the roof becomes unstable and collapses forming a stack
  5. Overtime the waves erodes the stack which falls over leaving behind a stump
