1. How is a wave-cut notch formed?

  • Weathering weakens the top of the cliff, while the sea widens a fracture in the base of the notch
  • The sea attacks the cliff at low tide, forming a cave
  • The sloped beach is formed by deposition
  • Weathering of the top of the cliff causes it to collapse

2. What is abrasion?

  • A chemical reaction between the rocks and the seawater
  • When softer rock gets worn away quicker than harder rock
  • When waves bring dirt or sand with them, which rubs away the cliff like sandpaper
  • When rocks break into each other on the sea floor and produce smaller bits

3. What is attrition?

  • When rocks break into each other on the sea floor and produce smaller bits
  • Larger rocks being deposited on the back shore
  • A chemical reaction between the rocks and the seawater
  • Sand picked up by the wind brushes against the cliffs eroding it

4. What are the physical types of weathering?

  • Onion skin and freeze-thaw
  • Vegetation and animals
  • Slumping and soil creep
  • Freeze-thaw and chemical weathering

5. Which Costal features does deposition cause?

  • Headlands, bays and bars
  • Spits, tombolos and beaches
  • Beaches, stacks and stumps
  • Bars, lagoons and wave-cut notches
