For this section you need to know the case study of one range of fold mountains – the Alps. You need to be able to explain the ways in which they are used – farming, hydroelectric power, mining, tourism and how people adapt to limited communication, steep relief and poor soils.
Physical problems of fold mountains
- Accessibility: roads and railways are expensive and difficult to build. They’re often disrupted by rock falls, avalanches and bad weather.
- Soils: typically thin and infertile.
- Climate: increased height means that climate is colder, windier and wetter. The growing season is short and it is often impossible to grow crops at high levels.
- Relief: mainly high and steep with frequent rock outcrops and many mountain valleys are narrow and gorge like. There is little flat land available for farming and building settlements.
The Alps are located in Central Europe and border Austria, Italy, Switzerland, Germany and France. They were formed by the African plate psuing against the Eurasian plate. As it moved sediments in Sea of Thethys (the geosyncline between the plates) were squeezed upwards to form the Alps. The highest peak is Mont Blanc near the Franco-Italian border at 4810m but many other peaks are also above 3800m. It is the source area for some of Europe’s great rivers e.g. Rhine and Rhone.

How do humans use the Alps?
Hydro-electric power: steep slopes, high precipitation and summer melting produce fast flowing rivers and narrow valleys mean that the rivers are easy to dam. This makes the Alps ideal for generating hydro-electric power which then in turn attracts industry to the area. Some electricity is also exported to other regions to supply towns and cities (60% of Switzerland’s energy comes from HEP in the Alps).
Farming: Most farms are located on the sunnier and warmer south-facing slopes. The traditional pattern of farming is a type of dairy farming called transhumance. This is where animals are moved according to the season. In the summer cattle are taken up to the high alp to graze which allows hay and other fodder crops to be grown on the flat land in the valley floor when the soils are at their deepest and most fertile. In winter the cattle return to th farm on the valley floor where they are kept in cattle sheds and stall fed the fodder crops which were grown in the summer. There has been many changes to the traditional way of farming. Cable cars installed for tourism are now being used to bring milk to co-operative dairies on the valley floor each day rather than farmers staying on the alp all summer and turning the milk into butter and cheese (longer lasting). Farmers also buy in additional feed stuffs so that their cattle can stay on the valley floor all year.
Forestry: coniferous forest cover many of the slopes especially north-facing ones. Wood, as a plentiful resource, has always been the main building material and winter fuel in the Alpine region. Most saw mills are located on the valley floor near rivers.
Tourism: the Alps have physical advantages for tourism all year round. In summer walkers and climbers are attracted to the stunning scenery in the area. Theree are large glacial lakes on the valley floors and beautiful scenery with snow-capped peaks. Examples of main summer resorts are Interlaken and Lake Garda. In winter the snow attracts skiiers to the area. Weather conditions are perfect as in between the days of heavy snowfall are many sunny, crisp and clear days. The flatter land on the high level alp allow for easy building of hotels, restaurants, ski lifts and other facilties. Steep sided slopes above the resorts are perfect for skiing amid great mountain views. However, there is a concern that the Alpine winters are warming up and becoming less snowy.
How have humans adapted to living in the Alps?
- Farmers have adapted their practise to working in fold mountains by diversifying their techniques and using technology to move away from transhumance. As the valleys get more built up through tourism, the space available to farmers decreases so they have to design new methods of farming, such as introducing vineyards or providing campsites for tourists to help boost their income.
- As the countries are rich problems like communication and transport have been overcome. Modern road tunnels e.g. Mont Blanc, St Bernard have replaced old routes over high passes. Many electrified railways link the Alps to cities; rail tunnels under the Alps include the Brenner and St Bernard. Mountain cog railways, cable cars and ski lifts link the valley floor to high level benches and ski slopes above them.
- The greater overall usage of the Alps has meant that communication links, e.g. roads, has been improved making it easier to move around the Alps and ensure people can live and work more effectively. Even ski lifts and cable cars can be used to move around both people and also farmers’ animals.
- Locals have developed new ways of supporting tourism from building new resorts to offering different types of activities in the summer and winter, all to try and encourage people to visit the area. This provides jobs year round and a considerable income for the area.
- Energy companies have used the steep sided valleys to build dams, reservoirs and HEP plants to provide energy, using the regions natural landscape to provide more renewable forms of energy.
- Industry uses natural resources, particularly trees, to provide wood for a variety of uses. Deforested trees are replanted to preserve the resource and in doing so, long term employment is provided.
