Processes of coastal erosion

Processes of coastal erosion

Hydraulic Action is:

•  this is the sheer power of the waves as they smash against the cliff. Air becomes trapped in the cracks in the rock and causes the rock to break apart.

Abrasion is

• this is when pebbles grind along a rock platform, much like sandpaper. Over time the rock becomes smooth.

Attrition 

• this is when rocks that the sea is carrying knock against each other. They break apart to become smaller and more rounded.

Solution

• this is when sea water dissolves certain types of rocks. In the UK, chalk and limestone cliffs are prone to this type of erosion.
