cliff profile and rate of retreat

Question 1

where are steep cliffs most commonly found?

Answer 1

where rocks are strong and fairly resistant to erosion and high energy environment

Question 2

where are gentle cliffs found?

Answer 2

areas with weaker rock which are less resistant to erosion with low energy waves and a short fetch commonly found in low energy environments

Question 3

what is the two things rate of retreat is dependent on?

Answer 3

marine factors (fetch, beach, wave energy)

terrestrial factors (subaerial processes, geology, rock strength)

Question 4

what is a negative feedback loop which could help protect and restore a coast?

Answer 4

during a storm part of a cliff may collapse
material produced will protect the base of the cliff from marine erosion
reducing further cliff recession
