Hydraulic action will
exploit these weaknesses.
Because chalk is a
sedimentary rock, lines of
weakness run throughout
the headland.
This is a chalk headland.
Between low and high
tide, waves will attack the
base of the headland.
HT
The process of corrasion
will undercut the base of
the cliff, forming a wave
cut notch.
LT
The undercutting by
corrasion will make the
cliff unstable.
HT
This creates small caves
which are enlarged over
time by erosion.
LT
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
It may collapse leaving a
stack.
LT
Continued erosion of the
base of the stack may lead
to its collapse, resulting in
a stump.
