Key Info
  • Coastlines - erosion
  • Duration: 03:42
  • An explanation of erosion and how it affects the coastline. When waves hit the rocks erosion takes place, which changes the shape of our coastlines. Over time as the waves and rocks erode the cliffs, a notch is created which is called undercutting. When this notch becomes too heavy it will break off and crash into the sea. Different parts of the rock face are eroded at high and low tide. If high winds meet a high tide the erosion will be greater. Different coastal features such as caves, arches and stacks are created by erosion.
