The country is landlocked, though it is close to the Black Sea; at its closest point it is separated from the Dniester Liman, an estuary of the Black Sea, by only 3 km of Ukrainian territory. While most of the country is hilly, elevations never exceed  – the highest point being the Bălănești Hill. Moldova's hills are part of the Moldavian Plateau, which geologically originate from the Carpathian Mountains. Its subdivisions in Moldova include the Dniester Hills (Northern Moldavian Hills and Dniester Ridge), the Moldavian Plain (Middle Prut Valley and Bălți Steppe), and the Central Moldavian Plateau (Ciuluc-Soloneț Hills, Cornești Hills—Codri Massive, "Codri" meaning "forests"—Lower Dniester Hills, Lower Prut Valley, and Tigheci Hills). In the south, the country has a small flatland, the Bugeac Plain. The territory of Moldova east of the river Dniester is split between parts of the Podolian Plateau, and parts of the Eurasian Steppe.
