• High tidal ranges allow waves to reach the shore.

• Lower tidal ranges produce deprossosition at a smaller elevation interval.

• The tidal range is influenced by the size & shape of the coastline. 

• Cliffs coasts give dispersed energy.

• High clifs breaks wave energy.

• Air and water cracks in the rock, forcing the rock apart, breaking it down.
