COASTS Bk3 - Erosional Landforms Flashcards
1
Q
What is a wave cut platform?
A
A gently sloping (<5%) relatively smooth marine platform caused by abrasion at the base of the cliff
2
Q
What processes + features produce wave cut platforms?
A
- destructive waves
- abrasion and hydraulic action
- wave cut notch
- wave cut platform
3
Q
Why does a negative feedback loop develop in the coastal system? > linked to wave cut platforms
A
As wave energy dissipates, the wider the wave cut platform. Erosive power at the base of the cliff decline and the rate of retreat slows
4

A
An inlet, a gully or a narrow and deep cleft in the face of a cliff. Geo’s are common on the coastline of Shetland and Orkney islands
