Wave Cut Platform

Question 1

Waves that form a a wave cut platform (2)

Answer 1

Destructive waves break at the foot of a cliff
Energy is concentrated over a fairly small area

Question 2

Wave cut notch - erosion (2)

Answer 2

Hydraulic action and corrasion concentrated close to the high-tide line
Cliff becomes undercut = wave-cut not

Question 3

Cliff above notch (2)

Answer 3

Weathered and under stress due to the lack of support from below
Over time = cliff collapses

Question 4

Collapses of cliff leads to what (3+)

Answer 4

Over a series of collapses = wave- cut platform begins to develop
Forms between the high and low water marks
Platform is smooth and flat - slopes at less than 5°

Question 5

What happens overtime one platform is formed (3+)

Answer 5

Waves break further and further out to sea
Travel over more and more platform = energy is dissipated when reaches the bottom of cliffs
Rate of cliff erosion decreases + the platform ceases to grow

Question 6

Answer 6

Unlikely to grow wider than 500 m

Question 7
