Coastal erosion is the wearing away of land, or the removal of beach, by wave action.
Mix & Match
When waves pick up sand, pebbles rock and boulders and throw them at the cliff. These work like sand paper or wrecking balls.
Waves force air and water into cracks.
Sea water dissolves soluble material from the cliff.
Rocks and boulders already eroded at the bottom of the cliff are knocked together and are worn down into smaller pieces.
We are going to look at 2 iconic landforms on the coast line. Wave cut platforms and cave, arches and stacks.
There are weakness in all types of cliff, hydraulic action gets into the crack and begins to…..
After further erosion in the form of H…..A….., C…. & A ….. The stack collapses and becomes a stump
