Turan Plains (Lowlands)

 The Turan lowlands are extensive lowland plains in southwestern Kazakhstan and the north-western parts of Uzbekistan and Turkmenistan. It is bounded by the Saryarqa (Kazakh uplands) in the north, the outliers of the Tien Shan, Pamir, and Alay mountains in the east, the Kopet-Dag Range in the south, and the Caspian Sea to the the west it is transversed by the lower courses of the Syr Darya and Amu Darya both of which drain into the Aral Sea. 

The plain encompasses two deserts, separated by the valley of the Amu Darya the Karakum and the Kyzylkum. The deserts comprise fine-grained sedimentary rocks overlain by extensive sand dunes and sand sheets.

The relief of the Turan Lowland is characterized by the alternation of accumulative lowlands and plains with relatively weakly dissected table plateaus the Usturt, Krasnovodsk and the Zaunguz Karakum. Most of the Turan Lowland has a sharply continental, desert climate.
the southern part has a more subtropical climate. 

Vegetation is  sparse, comprising xerophytic (drought-resistant) scrubs and short grasses. There are seasonal pasture lands in the margins of the deserts and irrigated agricultural land along rivers and oasis within the basin.
