Why do areas along the coast erode differently?

The coastline consists of parallel bands of hard and soft rock.

The bands of soft rock are eroded much more quickly than the bands of harder rock to form bays and headlands.

The headlands will be eroded back as a result of wave action.

Eventually, the coastline will become straight again and the whole process of erosion will start again. https: //www. youtube. com/watch? v=q 2 WJ VBc. YYyg

Wave cut platforms Waves erode a steep coast through processes like hydraulic action and abrasion.

Wave cut platforms • The waves erode along lines of weakness in the rock face to form a notch.

Wave cut platforms • Continued erosion enlarges the notch and causes its roof to collapse, and a cliff is formed.

Wave cut platforms Further undercutting at the base of the cliff results in an overhanging cliff which eventually collapses.

Wave cut platforms • As the steep cliff retreats landwards, a flat terrace at the foot of the cliff is exposed --wave-cut platform. https: //www. youtube. com/watch? v=k. OOb c. Xpv. Uu. Y Flat terrace (wave cut platform)
