Three rivers which flow northwards into the Arctic Ocean — Ob, Yenisey and Lena, have together built this plain. These marshy and swampy lowlands are also called as the Great Siberian plain. The lower courses and mouths of the rivers freeze in winter. So, water coming from the upper courses in warmer latitudes spreads out over large part of the plains. Another low lying land exists south of the Siberian Plains in Central Asia called as the Turan Plain. This plain is an area of inland drainage and is drained by rivers AmuDarya and SyrDarya.
