Текст:
The Urals - a borderline between Europe and Asia-are a mountain chain which appeared many years ago as a result of tectonic activity. As time went on, the mountains were being destroyed by the action water, sun and air. As a result, the highest mountains are only one thousand metres high. One more consequence is that the greatest deposits of ores came to the surface of the Earth. The fact that they were easily accessible stimulated the development of plants. The Urals mining industries began during the time of Peter the First. In the 18th century the Urals, with their high quality ores and rich forests (a fuel for plants) played the greatest role in the world industry. Russia exported metal even Great Britain. The modernisation of the Ural industry began with Magnitogorsk plant, built near the mountain Magnitnaya, rich in metallic ores. Latter, many engineering plants were built in the region. The greatest plants are situated in Magnitogorsk, Nizhniy Tagil, Chelyabinsk and Novotroitsk. At the beginning of the 20th century the Ural metal industry suffered a crisis because of the shortage of coal. But the delivery of coal from Kuzbass solved the problem. It must be mentioned that about 70 metals and minerals were first discovered in the Ural mountains. Large deposit of iron, copper, lead, zinc, nickel, titanium, wolfram and many other metals characterise the region. Nowadays some of the deposits are exhausted, and the plants work on the ore from new layers(Kazakhstan, Siberia). But nevertheless, the Urals are the region with great history, traditions and experience, and hopefully it will have new stages of development.
