Figure 1 shows the upland areas of the UK and the maximum extent of ice in the last glacial period.
Using Figure 1 and your own knowledge, explain how glaciation has contributed to the diversity of landscapes in the UK.
Model answer
Figure 1 shows that during the last glacial period, ice covered the UK north of a line running from south Wales and the Severn estuary, across the Midlands near Birmingham, to the Wash. Scotland, northern England, most of Wales and Northern Ireland were all under ice, and almost all the upland areas were covered, except Dartmoor and Exmoor in the south-west.
In the uplands, glaciers eroded the land deeply, creating rugged landscapes that are very different from those further south. In the Lake District, Snowdonia and the Scottish Highlands there are corries, sharp arêtes and pyramidal peaks, and the valleys were widened and deepened into U-shaped troughs, often with ribbon lakes and hanging valleys. In lowland areas covered by ice, glaciers deposited thick layers of till (boulder clay), forming gently rolling landscapes such as those of Holderness, which often have fertile soils.
South of the ice limit, there was no glacial erosion. These landscapes were shaped instead by rivers and by weathering in very cold conditions near the ice, producing gentle features such as the rolling chalk downs with their dry valleys. Glaciation therefore adds to the contrast created by geology: the north and west have rugged, glaciated uplands, while the south and east have softer, gentler lowland landscapes.
Explanation
Level 3 answers use the map to say where the ice reached, then explain glacial erosion in the uplands and deposition in some lowlands, contrasting both with the unglaciated south. Named examples (the Lake District, Holderness, the chalk downs) add precision. Answers that just list glacial landforms without linking them to the diversity of UK landscapes stay in Level 2.
