  1. Distinguish between the processes of erosion and weathering in an area undergoing glaciation.

Erosion is the wearing away and removal of material by a moving force. In an area undergoing glaciation the moving force is the ice. The processes of erosion include plucking and abrasion. On the other hand weathering is the breakdown and decay of rock in situ, with no movement involved. The processes of weathering include freeze-thaw and dilatation. Erosion moves rocks from one place to another, whereas weathering simply breaks rock particles down. So the difference between the processes of erosion and weathering it that the processes of erosion involve movement, whereas the processes of weathering do not.

2.  Examine the impact of glacially eroded landforms on human activity

Glacially eroded landforms have many different impacts on human activity, some positive and some negative. These impacts range from transport to industry in both rural and urban areas.

Transport is an aspect of human activity affected by glacially eroded landforms. U shaped valleys are glacially eroded landforms which have great advantages for transport as they provide natural routeways for through upland areas. So roads and railway lines can be constructed, linking major towns together. For example the A591, which is the main road through the Lake District, follows a glacial trough. The Penrith to Cockermouth railway, now dismantled, followed glacial valleys. So glacial valleys can provide natural routeways however they do have a disadvantage to transport. It is very difficult to find a routeway between parallel valleys, so if two settlements are in parallel valleys, it is likely that to connect the two it would mean going round the valley.

Tourism is hugely affected by glacially eroded landforms. The tourism industry has had huge growth in recent years which has brought many economics benefits to mountain regions. The multiplier effect is an economic benefit brought through tourism. Visitors are attracted by the spectacular glacially eroded landforms such as pyramidal peaks, corries, deep valleys, arêtes and hanging valleys. Britain is rich in these landforms which provide scenic value to areas like the Lake District. The glacial landforms not only bring tourists seeking scenic value to areas, but also provide a great opportunity for hill walkers, climbers, and skiers. Many areas have ...
