Over 1,800 kilometers that separate the southern border of Kazakhstan from the north, followed by several landscape zones: steppe, steppe, semidesert and desert. In the west, the territory of Kazakhstan borders the Caspian Sea in the east - the taiga Altai, and in the south - with the high peaks of the Tien Shan. The lowest point - Karagiye on Mangyshlak (132 meters below sea level), the highest - Khan Tengri peak in the mountains (7000 meters above sea level). Three major rivers - Irtysh, Tobol and Ishim - carry their water in the Arctic Ocean, the other Kazakh rivers empty into inland water bodies: the Caspian Sea, the Aral Sea, Balkhash, or simply spread out over the steppe or desert. The western part of Kazakhstan is almost entirely flat, and the east - mostly mountainous, besides such as the high mountains of the Tien Shan and Altai, considerable space is occupied Tarbagatay Saur, Kazakh low hills, Kokshetau hill.
