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.
