GCSE Geography · key term
A hollow eroded into coastal rock as waves enlarge a weakness such as a crack.
Used by AQA, Edexcel and OCR
Specification 3.1.3.2 · Paper 1
Revise: Erosional and Depositional LandformsErosion wears away the coastline, creating features such as cliffs and caves. Deposition occurs when moving water or wind loses the energy needed to carry sediment, building features such as beaches and dunes.
Specification 1.4 · Paper 1
A hollow eroded into a cliff or headland as waves enlarge a weakness in the rock.
Revise: Coastal LandformsContinued erosion enlarges a crack into a cave.
Paper 2
A hollow eroded into a coastal cliff or headland, often along a joint or fault.
Revise: Geological Structure and Erosional LandformsOver time, a crack can widen and deepen into a cave.
Specification 3.2a · Paper 1, Paper 3
A hollow eroded into coastal rock as waves enlarge a crack or other weakness.
Revise: Coastal Landforms: Erosional and Depositional FeaturesRepeated erosion widens a crack into a cave, a hollow extending into the headland.
Use hydraulic power and abrasion to explain erosion of cliffs and headlands. Attrition wears down transported fragments; it does not directly cut a cave into a cliff.
Use hydraulic action and abrasion to explain erosion of a cliff or headland. Attrition wears down transported fragments; it does not directly cut a cave into a cliff.
Explain the stages between landforms: a cave breaks through a headland to form an arch; collapse of the arch roof leaves a stack.
