Sea water contains salt- when it lands on rock, the water evaporates leaving the salt. The salt crystals grow and create stress in the rock, causing it to break into small fragments.
1 of 9
Acid Rain
Rain is slightly acidic; polluted air is very acidic. When rain falls on rock, it can react with minerals causing them to dissolve and decay.
2 of 9
Biological Weathering
Roots can grow into cracks and split the rock apart.
3 of 9
Hydraulic Action
Force of water hitting the rocks, forcing pockets of air into the cracks.
4 of 9
Corrosion
The dissolving of soluble rock.
5 of 9
Abrasion
Waves picking up stones and hurling them at the base of cliffs, wearing them away.
6 of 9
Attrition
Material carried by the water becomes rounder and smaller as it knocks together with other sediment.
7 of 9
Slumping/Rotational Slip
Happens when the bottom of a cliff is eroded by waves. Makes cliff steeper. The cliff slips down in a rotational manner often triggered by saturated soil.
8 of 9
Rock Fall
When rocks fall suddenly under gravity and collect at the base of a cliff.
