negative feedback (bays)

Question 1

1) there’s different rock strengths… which leads to… formation of… where what exists? what is dominant in these areas?

2) what does this increase in the headlands? what does it reduce in the bays? what happens as wave refraction takes place? what is protected?

3) eventually what happens to the headlands? what happens to the bays? what does it lead to? but what happens with time?

Answer 1

1) Due to the different rock strengths, erosion leads to the formation of headlands where resistant rock exists and bays where unconsolidated rocks and clays are dominant.

2) This increases the forces of erosion on the headlands and reduced erosion in the bays as wave refraction dissipates wave energy and a beach protects the coastline behind.

3) Eventually the headlands are worn away, which then again increases erosion within the bays. This would
lead to dynamic equilibrium if conditions stayed constant, but of course over time they will vary.
