Erosinal Landforms

Question 1

How are wave-cut notch/platform’s formed?

Answer 1

-cliffs of solid oak recede over time
-may leave a basal shelf (uncovered at low tide&submerged at high tide)
-area of recession
-this wave-cut platform represents the base of a cliff that lies below the dominant intertidal zone of erosional processes
-cliff line retreats, wave-cut platform becomes wider and has an increasing frictional effect on advancing waves
-develops a negative feedback loop, erosive power at base of cliff declines and rates of retreat slows
