Glaciated Landscapes and Change
Relict glacial landscapes, and polar against temperate glaciers
- 3 things to know
- Paper 1
Overview
Recall questions on the landforms left behind in Britain, and on what separates a polar from a temperate glacier.
What you need to know
Answer each one before you reveal it.
What are relict glacial landscapes?
What is the key criterion for distinguishing between ice sheets and ice caps?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What are relict glacial landscapes?
Model answer
Landforms created by past glaciation that remain visible after ice has retreated, providing evidence of former glacial activity.
- 2
How do cirques provide evidence of relict Pleistocene landscapes in upland areas?
Model answer
These armchair-shaped hollows with steep back walls indicate where glaciers once accumulated and eroded the mountainside.
- 3
What do arêtes indicate about past glacial activity?
Model answer
These knife-edge ridges form between two cirques or glaciers, indicating where ice eroded both sides of a ridge during the Pleistocene.
- 4
How do pyramidal peaks serve as evidence of former glaciation?
Model answer
These sharp, pointed summits form where three or more cirques erode back towards a central point, indicating past glacial erosion from multiple directions.
- 5
What do hanging valleys reveal about relict glacial landscapes?
Model answer
These tributary valleys with floors elevated above the main valley indicate differential erosion by glaciers of different sizes during the Pleistocene.
- 6
How do ribbon lakes provide evidence of past glaciation?
Model answer
These long, narrow lakes occupy over-deepened sections of glacial troughs, indicating where ice erosion was concentrated during the Pleistocene.
