Transcript of How do people use the Andes (fold mountains)

by Ryan McDonnell How do people use the Andes (fold mountains)? Farming Hydroelectric power The Andes mountains contains a rich mix of minable materials that are both very valuable and very useful to man. There are large deposits of Coal, oil and natural gas, iron ore, gold, silver, tin, copper, phosphates and nitrates and Bauxite within the Andes mountains. The Yanacocha gold mine in Peru is the largest gold mine in the world. It is an open cast mine and the rocks containing the gold are blasted with dynamite. The rock is then sprayed with toxic cyanide and the gold extracted from the resulting solution. This can contaminate water supplies. The nearby town of Cajamarca has grown from 30,000 when the mine started to 240,000 people in 2005. Mining On the Andes people who live there do many things. One of these is farming. They grow potatoes mostly and these will then be a main food source for the family . They grow these by creating flat land on the side of the hill and then they stop the fertile soil from falling with a tall straight wall that supports the flat land. This flatland is good for farming as it retains water and soil from rolling down the hill.These man made flat lands are called terraces, built by the subsistence farmers.Some other things are grown for example: cotton , rice and soybeans.these areas of agriculture possesses little water therefore the farmers need to administer it by hand and use it smartly and cautiously.But how do they get the materials they need up the mountains? Well they use llamas which have the ability to carry up the mountain much more than a human and they have done this for hundreds of years. This is how hydroelectric power would be generated on an area of fold mountain using a dam! The deep valley and rivers of the Andes give it huge potential as a region to produce hydroelectric power. The narrow valleys are ideal to dam as it cuts costs, and the steep relief increases water velocities allowing electricity generation. Snow melt fuels most of the water provision, but this means that hep production can be reduced to small amounts in winter. The Yuncan dam project dams the Puacartambo and Huachon rivers in northeast Peru, while the el Platinal project will begin construction in 2009. This is a man on the Andes mining with the cyanide spray. This is a stall and most of the items here will be made out of cotton for sale to the public.The cotton will be grown on the fold mountains by the farmers who then sell the cotton to the stall owners who turn it into items like this to sell on. Tourism Tourism is a massive industry for Peru and the country has a lot to offer. In the East you can take part in Eco-tourism activities in the Amazon Basin, as found along the Madre De Dios River near to Puerto Maldonado. Peru has some fantastic coastline as well, but the highlight of Peru is undoubtedly the Inca Trail. the natural attractions are the main thing that drags people back year in year out as it is a true wonder and a mystifying beauty. Tourism is good for Africa as it can create more jobs for people there. this gets the countries in africa that people are going to more income for an improvement to try to help the countries become more economically developed.
