Hydraulic power

The sheer power of the waves eg smashing against a cliff. 


Trapped air is blasted into holes and cracks in the rock eventually causing the rock to break apart (cavitation).

1 of 5

Corrasion

The effect of rocks being flung at the cliff by powerful waves. 


The rocks act as erosive tools by scraping and gouging the rock.

2 of 5

Solution

The dissolving of rocks such as limestone and chalk.

3 of 5

Attrition

The knocking together of pebbles, making them gradually smaller and smoother.

4 of 5

Abrasion

The 'sandpapering' effect of pebbles grinding over a rocky platform, often causing it to become smooth.
