Cliffs + Wave cut platform
Cliffs
As the
waves continue
to pound and
erode the coast
, the notch gets wider and deeper and eventually becomes unsupported.
As a result, the
cliff collapses
, often
by mass movement
such as a rockfall.
This process continues and the
cliff retreats,
leaving a
wave-cut platform at the base
of the cliff.
An example
of a wave-cut platform is
Dancing Ledge
.
Wave cut platform
Waves attack the coast and erode the cliffs by two main erosional processes;
hydraulic action
is when the
force of the water compresses air
and pressure on the cliff causes materials to be dislodged.
Secondly by solution which is when soluble rocks react with acids or salts in the water.
Waves
mostly
attack the base
of the
cliff
which then gets
worn away the fastest.
The
foot of the cliff is undercut
, and a
wave-cut notch
is formed.
