    1. Glaciation Revision

    3. What are the features of glacial erosion? U-shaped Valley Hanging Valley Corrie Tarn (Corrie Lochan) Pyramidal Peak Arete Ribbon Lake Miss-fit stream Truncated Spur Scree

    4. A very common glaciation question featured in 2001: a) Using the Torridon map provided, match each of the glacial features in the table below to the correct grid square. Choose from: 952588, 923580, 852585, 860601, 925576 (3marks)     THEN b) Explain how one of the glacial features listed in (a) was formed. You may use a sketch to illustrate your answer.

    6. How is a U-shaped valley formed?

    7. Along its journey down the valley a glacier would be joined by tributary glaciers. These smaller tributary glaciers contained much less ice and so were less powerful. They could not erode their valleys as deeply as the main glacier so, where they met, the tributary valley was left “hanging” above the main valley.

    9. How is a corrie formed?

    10. How is a Pyramidal Peak formed? a) three or more corries form around a peak, (processes are the same as for corries), b) where corrie sidewalls meet they form an arête (knife edge).

    11. Land uses in glaciated uplands Farming Forestry Recreational Water Sports Skiing Hydro-electric power

    12. Why is forestry good in upland areas? Because the land is generally unsuitable for farming due to poor soils and steep slopes so forestry would be a more profitable land use. Trees prevent soil erosion The best areas would be on the lower slopes near the main roads to provide access for transport and machinery. The higher mountainous area is less suitable due to colder growing conditions/poorer soil and the difficulty of using machinery on steep slopes. Attracts wildlife Benefits to tourism – forest walks etc.

    13. Farming in Glaciated Uplands U-shaped valley - flat or gently sloping land which could support arable farming Floodplains - soil is better (fertile) Communication systems (transporting goods to market and allowing workers on the farm access) Slopes - the main activity would be hill-sheep farming. Trees where the sheep can shelter On more mountainous land, commercial farming activity would be limited because of steep land, poor soils, cold weather and inaccessibility to markets.

    14. What would make an area good for….. Skiing? Good slopes Services (shops etc which you would find in a village) Communication systems (roads) Places to stay (village/town with hotels)

    15. Land-use conflicts National Parks Cairngorms skiing Loch Lomond and The Trossachs Vandalisim Littering Planning permision

    16. Different parties involved in Land Use Conflicts National Park Authority Environmentalists Local People Businessmen Local Businesses Users of the National Park – walkers etc

    17. Other land uses in Glaciated Uplands Quarrying Hydro-electric power Conflicts? Think about Environment Economy Social Sustainable Development
