Pre-Ural Plateau

The Sub-Ural Plateau (Poduralskoe Plato) is a low-elevation mountainous plateau mostly in west Kazakhstan and some northern parts are in Russia. It is also known as the Cis-Ural Plateau (Preduralskoe Plato). Its southern part is known as the Emba Plateau (Embinskoe Plato), after the Emba River that flows across it. In Kazakhstan, the majority of the plateau is within the Aktobe Region, with small northwester part in the West Kazakhstan Region. In Russia, a small northern part is within the Orenburg Oblast. The plateau is a gently sloping flatland with elevations ranging from 450m in the northeast and 100m in the southwest. It merges into the Caspian Depression in the southwest and merges with the Mugalzhar Range (southern continuation of the Ural Mountains) in the east. Its natural northern boundary is the valley of the east–west stretch of the Ural River. The northern part is dissected by deep valleys and ravines, in the south the watersheds are more flat and the network of ravines is less dense. In terms of vegetation the plateau is split between Eurasian steppe zone and Gobi-type desert zone. The watersheds near the Mugalzhar feature buttes (steep-sided flat-topped isolated hills), indicative of the elevations before the area was washed out. Rivers Emba
