wave cut platforms

Question 1

how are cliffs created?

Answer 1

•cliffs are created by coastal erosion and weathering
•resistant rocks form steep cliffs too.
•soft rock erodes quicker creating gently sloping cliffs

Question 2

how are wave cut platforms formed?

Answer 2

1. destructive waves erode the cliff through processes like abrasion
2. waves erode the cliff between the high and low tide lines
3. overtime, this erosion creates a wave cut notch
4. this notch gradually gets larger, the cliff above the wave cut notch is unsupported
5. mass movement (the downward movement of material under the force of gravity) occurs as a result of gravity and the cliff retreats
6. the wave cut platform is the uneroded section of the original cliff at the base, the process starts to repeat with a new notch forming
7. the cliff continues to retreat
