The document discusses how people use the Alps fold mountain range through farming, tourism, and hydroelectric power. Farming occurs mainly in valley bottoms and involves dairying, viticulture, and growing hay and cereals. Summer pastures are located at higher elevations. Tourism includes skiing, climbing, hiking, and sightseeing. Hydroelectric power is also generated using the mountains. The Alps formed 30-40 million years ago through compression and were later altered by glaciation during the last ice age.
