Coastal Erosion Landforms Flashcards
What is a landform?
A feature of the landscape that has been formed or sculpted by the processes of erosion, transportation and deposition.
What is erosion?
Wearing away and removal of material by a moving force, such as a breaking wave.
What is transportation?
The movement of eroded sediment.
What is deposition?
When material being transported by the sea is dropped due to the sea losing energy.
What is it called when material being transported by the sea is dropped due to the sea losing energy?

What factors influence coastal landforms?
Geology and the geological structure.
How does geology influence coastal landforms?
Some rocks are tougher and more resistant than others.
How does the geological structure influence coastal landforms?
The layers of rock are folded or tilted.
What are the features of hard rock?
It is more resistant, impermeable and erodes about 20mm per year.
What type of rock is more resistant, impermeable and erodes about 20mm per year?
Hard rock.
What are the features of soft rock?
Less resistant, erodes about 20cm per year and is permeable.
What type of rock is less resistant, permeable and erodes about 20cm per year?
Soft rock.
