erosionsl landforms Flashcards
What are erosional landforms?
Distinctive features caused by coastal erosion, including headlands, bays, caves, arches, and stacks.
What characterizes headlands and bays?
Developed on coastlines with a mix of hard and soft rock; often occur where cliffs have fault lines or joints.
What are cliffs in coastal landscapes
Common coastal features shaped by weathering and erosion; consist of hard rock (like chalk) that erodes slowly, forming steep cliffs, and soft rock that erodes easily, creating gently sloping areas.

How do caves and arches form?
Caves form when waves erode weaknesses in the rock, such as joints or faults; arches form when two caves erode back towards each other and meet.
What are wave-cut platforms?
Flat rock areas at the base of cliffs, formed as cliffs erode and retreat due to wave action.
How is a stack formed?
A stack is formed when an arch collapses due to erosion from waves, leaving a vertical column of rock.
How do prevailing winds affect coastal erosion?
High-energy waves driven by prevailing winds (often from the south-west) contribute to the erosion of coastlines
What should you look for on an OS map to identify a headland?
The term ‘point’ in the name often indicates a headland, such as Peveril Point near Swanage
