It is largely lowland in the north and west, hilly in the center (Kazakh Hills) , and mountainous in the south and east (Tian Shan and Altai ranges).

Most of the region is desert or has limited and irregular rainfall.The population of Kazakhstan consists mainly of Muslim Kazakhs and Russians; there are smaller minorities of Ukrainians, Germans, Uzbeks, and Tatars. Kazakh, a Turkic language, is the official tongue, but Russian is still widely used.Despite Kazakhstan's largely arid conditions, its vast steppes accommodate both livestock and grain production. Wheat, cotton, sugar beets, and tobacco are the main crops. The raising of cattle and sheep is also important, and Kazakhstan produces much wool and meat. In addition, there are rich fishing grounds, famous for their caviar-producing sturgeon, in the Caspian, although these have been hurt by overfishing.The Kazakh Hills in the core of the region have important mineral resources. Coal is mined at Qaraghandy and Ekibastuz, and there are major oil fields in the Emba basin. The country's industries are located along the margins of the country. Steel, agricultural and mining machinery, superphosphate fertilizers, phosphorus acids, artificial fibers, synthetic rubber, textiles, and medicines are among the manufactured goods. Temirtau is the iron and steel center. The Baikonur (Bayqongyr) Cosmodrome in central Kazakhstan was the Soviet space-operations center and continues to serve Russian space exploration through an agreement between the two nations. The main trading partners are Russia, Ukraine, and Uzbekistan.
