Q

Describe how Coastal Erosion has effected Mappleton

A
  • Further south, the rate of erosion has increased significantly, because of material which is being carried south is not being replaced as it is trapped between the groynes

Q

Have the cliffs been protected?

A
  • No, as there is no beach to protect them.

- Even during a heap tide, the sea reaches the base of the soft cliffs and erosion occurs
