glacial eroded landforms

Extracts from this document...


June 2002 - past paper (1) 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. ...read more.


This has led to average house prices surpassing �300,000. For local people this is a negative effect as they cannot afford to live on the island. However the money generated from tourism can be put into maintaining footpaths, for example on the Isle of Arran, footpaths were maintained, costing thousands of pounds. Another human activity affected by glacially eroded landforms is agriculture. Pastoral farming is the predominant agriculture, as the steep terrain and shallow soils in glacial areas are unsuitable for arable farming. Areas of glacial landform provide the necessary requirements for grazing animals, however there it is generally not suitable for arable farming. Although glacial troughs can provide flat valley floors in otherwise hilly areas which are suitable for arable farming. For example Yew Tree Farm, St Johns, in the Keswick area has dairy farming taking place on the flat valley floors. Lodgement till which has built up from successive glaciations covers much of East Anglia. Chalk from the underlying bedrock mixed with the overlying till forms a 'chalky boulder clay' soil. This is highly suitable for cereal cultivation. So glacial landforms do have benefits to agriculture, they provide areas for pastoral farming as well as soils and flat areas for arable farming. ...read more.


So this slate had huge economic benefits to the local area and economy. In lowland areas, glacial activities also benefit industry. Outwash deposits from ice sheets provide sand and gravel for the construction industry. However in order to extract raw materials such as slate, accessibility is a key issue. There must be enough infrastructure in the upland areas to transport the materials once they have been quarried or mined. However with such landforms as ar�tes and pyramidal peaks it is difficult. Glacially eroded landforms have a huge impact on human activity. The positive impacts include increased tourism resulting in the multiplier effect, and the exposure of raw materials. Settlements may also benefit from glacial eroded landforms as settlements can use fluvioglacial rivers. Transport can benefit from the eroded valleys for roads and railways, as does agriculture as the flat-floored valleys provide flat land for arable farming. The negative impacts of glacially eroded landforms include the difficulty of transport in upland areas, the limitation of arable farming as the land is mostly hilly and the instability of steep slopes caused by tourism. The accessibility to the raw materials is restricted due to glacial landforms such as corries, glacial valleys and pyramidal peaks. So it is clear that glacially eroded landforms have many positive and negative impacts on human activity. . ?? ?? ?? ?? Chris Stott ...read more.

It is where the ice again expands at ground surface displacing rocks and soils producing hills and valleys "a horizontal dislocation".
