This is a chalk headland.
Because chalk is a sedimentary rock, lines of weakness run throughout
the headland.
Hydraulic action will exploit these weaknesses.

Between low and high tide, waves will attack the
base of the headland.

LT
The process of corrasion will undercut the base of the cliff, forming a wave
cut notch.

The undercutting by corrasion will make the
cliff unstable.
HT
LTThis creates small caves which are enlarged over
time by erosion.

Caves develop on either side of the headland.
HT
LT
These caves erode back through the headland and
meet, forming an arch.

Continued erosion at the base of the arch will cause
the roof to become unstable.
HT
LTIt may collapse leaving a stack.

Continued erosion of the base of the stack may lead to its collapse, resulting in
a stump.
