Glaciated Uplands
Explain glacial erosion and recognise corries, arêtes, pyramidal peaks, truncated spurs and U-shaped valleys.
How to study National 5 Geography
Start from located evidence, identify the geographical process, develop each causal link and test management against the people and environments affected.
Core concepts
Concept 1
Glacial erosion includes plucking and abrasion, with freeze–thaw weathering supplying debris.
Exam cue: Name the process and show how it changes the rock or valley.
Concept 2
Corrie erosion can steepen back walls and deepen basins; erosion on adjacent sides can leave arêtes and pyramidal peaks.
Exam cue: Build the formation explanation in chronological stages.
Concept 3
A valley glacier widens, deepens and straightens a former river valley, truncating interlocking spurs and leaving a U-shaped cross-profile.
Exam cue: Link each landform to distinctive map, photograph or cross-section evidence.
Risk pitfalls and guardrails
Using erosion labels without describing their action.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Confusing a truncated spur with an interlocking spur.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Saying glaciers create mountains rather than reshape existing relief.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Memory anchors
Glacial erosion
Plucking removes blocks; abrasion scrapes rock with embedded debris.
Corrie
Armchair-shaped hollow with a steep back wall and over-deepened basin.
Arête
A narrow ridge left between two eroding corries or glacial valleys.
Pyramidal peak
A sharp peak left where three or more corries erode back.
Truncated spur
A former interlocking spur cut off by a valley glacier.
U-shaped valley
A wide, deep trough with steep sides and a broad floor.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
