1. What is attrition?

  • Larger rocks being deposited on the back shore

  • Sand picked up by the wind brushes against the cliffs eroding it
  • A chemical reaction between the rocks and the seawater

2. What are the physical types of weathering?

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

3. Which Costal features does deposition cause?

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

4. What is solution/corrosion?

  • A chemical reaction between the rocks and the cliff
  • Acids contained within seawater react and dissolve the cliff face
  • Wearing away of the cliff as rocks are thrown at it
  • Sand picked up by the wind brushes against the cliffs eroding it

5. 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
  • Weathering of the top of the cliff causes it to collapse
  • The sea attacks the cliff at low tide, forming a cave
  • The sloped beach is formed by deposition
