Wave Pounding: Immense force of waves causing the cliffs to weaken.
The acid in water causes the cliffs to erode
Holes inside rocks by erosion causes it to become bigger and bigger until an arch is created.
Arch: A large gap in a cliff created by erosion.
Stack: When a part of the cliff grows too big to withhold it’s pressure and weight and breaks.
Stack: When the weight above exceeds what the arch can sustain and collapses causing a stack to remain
Stump: The erosion made on stacks causing it to erode leaving a stump
Created as sea caves grow landwards and upwards into vertical shafts and expose themselves towards the surface
