My dashboard always seems to be related to the subject I’ve been studying o.o Ok, here we go, some practice:
Headlands are formed because the rocks are resistant to erosion.
Bays are formed because the rocks are eroded by hydraulic action/abrasion.
The conditions at headlands are more vicious as they are exposed; the waves are destructive and the water level is deep. Deep water encourages erosion because the waves are high energy, and so the cliffs do wear down eventually.
At bays, the conditions are much more sheltered and calm; the waves are constructive and the water level is shallow. Shallow water encourages deposition because the waves have little energy, so that bit of the coast is built up again.
This means that the coastline will straighten itself out over time.
I’m pretty sure you all really wanted to know that, lol
