GCSE Geography · key term
The wearing away and removal of rock or sediment by moving water, ice or wind.
Used by AQA, Edexcel and OCR
Specification 3.1.3.2, 3.1.3.3 · Paper 1
The wearing away and removal of material by moving agents such as waves.
Revise: Wave Types and Coastal ProcessesCoastal erosion wears away and removes material.
The wearing away and removal of material by processes such as flowing water.
Specification 1.2, 1.3, 1.4, 1.6, 1.7 · Paper 1
The wearing away and removal of rock or sediment by moving agents such as ice or flowing water.
Revise: Physical Processes Shaping LandscapesErosion wears away and removes material. Deposition lays down material that has been transported. They often operate in sequence: weathering supplies fragments, ice or rivers carry them away, and those fragments are eventually deposited elsewhere.
The wearing away and removal of material by moving water or other agents.
The wearing away and removal of rock or sediment by processes such as wave action.
The wearing away and removal of material by agents such as flowing river water.
Paper 2
Revise: Visual Analysis and Geological Interpretation of Landscapes“The valley has steep sides and a broad, fairly flat floor” describes visible evidence. “Its shape is consistent with glacial erosion” interprets that evidence. A strong geographical explanation connects the two rather than simply naming a process.
The wearing away and removal of rock or sediment.
Specification 3.2a, 3.2b · Paper 1, Paper 3
The wearing away and removal of rock or sediment by moving water and the material it carries.
Revise: Geomorphic Processes: Weathering, Mass Movement, Erosion, Transport and DepositionWeathering weakens rock, while erosion by a river or waves can remove support from the bottom of a slope. Together, these changes make slope failure more likely.
The wearing away and removal of rock or sediment by moving water, waves, wind or ice.
The wearing away and removal of rock or sediment by moving water, waves or other agents.
Distinguish weathering in place from downhill mass movement and erosion by waves.
Solution has two roles: dissolving rock is erosion; carrying the dissolved material is transportation.
Distinguish weathering, which breaks down rock in place, from erosion, which wears away and removes material.
