In contrast, the removal of material necessary to allowthe reshaping
of the platform above a more resistant layer is damped by profile flattening.
The slope immediately above the more resistant layer becomes
shallower because it is anchored to the outcrop, and therefore its retreat
slows. This in turn reduces the slope of the layer above it. The effect
passes up the profile, but is governed by a lessening of slopes, steadily
decreasing the effectiveness of the erosive potential of the incident
waves. In both cases the reshaping is controlled by negative feedback
acting to re-establish a dynamic equilibrium, but the feedback factor is
very different between the two.
