Cliffs And Wave Cut Platforms Flashcards
What happens at high tide?
At high tide the base of the cliff is eroded.
What 2 erosional processes takes place at high tide?
At high tide the two erosional processes which take place are abrasion and hydraulic action.
When the base has been eroded what is left behind?
An undercut is left behind when the base has been eroded.
What does the undercut form?
The undercut forms a ‘wave cut platform’.
What forms above the notch?
An overhang forms above the notch.
What forms below an overhang?
A notch will form below the overhang.
What happens ,over time, to the overhang?
In time, the overhang will collapses into the sea.
Why will the overhang collapse?
The overhang will collapse due to weather and lack of support.
What can the collapse of the overhang create?
The collapse of an overhang can create a rockfall.
What happens to the eroded material?
The eroded material would be:
Further eroded and transported
What will the sea do after the eroded material has been transported?
After it has been transported the sea will continue to attack the base of the cliff.
When the sea continues to attack the base of the cliff what is formed?
A wave-cut notch is formed when the sea continues to attack the base of the cliff.
What will this continue cycle cause?
This continual cycle will cause the cliff to retreat.
When the cliff retreats what does this leave behind?
A wave cut platform is left behind when the cliff retreats.
When can the wave cut platform be seen?
The wave cut platform can be seen at low tide.
