Rates of erosion

Question 1

How does the width of the beach affect erosion?

Answer 1

beaches slow down waves, reducing their erosive power. A wide flat beach will protect cliffs more than narrow, steeper beaches

Question 2

How does the breaking point of the waves affect erosion?

Answer 2

a wave that breaks directly at the foot of a cliff causes the most erosion. Waves that hit the cliff before they break erode much less

Question 3

How does the aspect of the waves affect erosion?

Answer 3

if the coastline faces the dominant wind and wave direction, erosion will be faster.

Question 4

How does the fetch of the wave affect erosion?

Answer 4

waves with a longer fetch are much and higher and steeper and have more energy, causing the most erosion

Question 5

How does rock type affect erosion?

Answer 5

hard rocks are much more resistant than softer rocks
