The heartland of this region is affected by continentality, or continental effects ◦ The further land is from the ocean, the greater the range of temperatures and the drier a region will tend to be Air coming from the Atlantic loses most of its moisture as it moves further and further inland Weather systems coming from the south have little rainfall after they climb over the Himalayas and other mountains south of the region
Temps seldom reach upwards of 50° and sometimes as low as -90° F People use frozen rivers and lakes as roads during the winter Permafrost can reach depths of 1,500 ft.
Humid continental and subarctic climates dominate the north and east of the region The south east is semi arid and desert In Transcaucasia, moist air from the Mediterranean and Black Seas contributes to a subtropical climate zone
4 major regions ◦ Tundra In the arctic climates zone: mosses, lichens, small herbs and shrubs adapted to cold, harsh conditions ◦ Forest The Russian taiga is the largest forest region in the world Mostly coniferous trees Many fur bearing animals such as sable, fox and ermine South of the taiga, the forest transitions into deciduous forests
Steppe ◦ The temperate grassland that extends from southern Ukraine through northern Kazakhstan ◦ Chernozem makes this region primo agricultural land Desert ◦ In the western and central parts of Central Asia ◦ Kara Kum in Turkmenistan ◦ Kyzyl Kum in western Uzbekistan
The Aral sea is filled from two main rivers-the Amu Darya and Syr Darya In the 1950s, the water was diverted for cotton irrigation
Pesticides and fertilizers were picked up by runoff-rainfall not absorbed by the soil and deposited in the Aral Sea ◦ None of the original 24 native species of fish are left today Retreating waters of the sea exposed these fertilizers and pesticides as well as salt; wind storms dump these pollutants on neighboring populations ◦ Sharp increases in disease Saving the Aral Sea would mean taking half of the land out of cultivation ◦ Terrible hardship for farmers who depend on the field for their livelihood
Verkoyansk in Siberia has recorded temperatures from - 90° F to 94° F within the same year from winter to summer ◦ When the snow and ice melt, pools of water and swampy conditions are breeding ground for mosquitoes and black flies ◦ In order to keep buildings from melting the permafrost and sinking into the soil, builders build them on stilts. “General Winter” has helped Russians ◦ In 1812, Napolean invaded Russia with over 100, 000 soldiers ◦ Caught by the winter, 90,000 soldiers lost their lives and Napolean’s effort was defeated ◦ A similar fate met the Germans during World War II
Siberia mirrors the history of our American “West” ◦ In order to improve travel into the region, the emperor order the building of the Trans-Siberian Railroad to link Moscow with Vladivostok Covered more than 5,700 miles and 7 time zones Built between 1891 and 1904 ◦ Within years, settlers poured into the region and resources poured out 5 million settlers Coal and Iron ore poured out ◦ The railroad also aided the political unity and economic development of the country
