coastal erosion, wave cut platforms, cliffs - Coggle Diagram
coastal erosion
caves
waves force their way into the cracks of the cliff face
sand and other materials grind away at the rock until it cracks and becomes a cave
hydraulic action and abrasion are the main processes in this
arch
will continue to erode and become bigger until it cant handle the top of the arch
when the arch collapses it leaves the headland on one side and a stack on the other
cliffs
where rock is weaker
the process of undercutting can accelerate the breaking of the cliff materials
wave cut platforms
wave cut notch
develops
undercuts the cliff above
leading to the cliff collapsing
inland retreat and creating a wave cut platform
stacks
weakens the structure and will eventually collapse to form a stump.
