Headlands + Bays

Question 1

Stage 1 - waves attack coastline

Answer 1

The geology of a coastline determines the rate of its erosion TMT headlands + bays are formed due to differential erosion

Question 2

Stage 2 - softer rock is eroded quickly

Answer 2

There are different bands of alternating rock types TMT rocks like clay and limestone are eroded at different rates. TIB clay is a softer rock than limestone so is eroded faster

Softer rocks erode backwards faster TMT they form sheltered bays containing beaches

Question 3

Stage 3 - harder rock juts out into the sea

Answer 3

The harder limestone areas are more resistant to erosion TMT they will stick out into the sea to form exposed headlands
