The village of Vel'ké Slemence is an anomaly, as it is split between Slovakia and Ukraine. Relief Most of its territory lies within the Great European Plain, while parts of western regions and southern regions lay within the Alpine system. In general Ukraine comprises two different biomes: mixed forest towards the middle of the continent, and steppe towards the Black Sea littoral. Major provinces include, Polesian Lowland, Dnieper Lowland, Volhynia-Podolie Plateau, Black Sea-Azov Lowland, Donets-Azov Plateau, Central Russian Upland, Carpathians, and Pannonian Basin. The western regions feature an alpine-like section of Carpathian Mountains, the Eastern Carpathians that stretches across Poland, Ukraine and Romania. The highest peak is Mount Hoverla, which at above sea level is the highest point in the country. Mountains are limited to the west, the southern tip of Ukraine on the Sea of Azov. The western region has the Carpathian Mountains, and some eroded mountains from the Donets Ridge are in the east near the Sea of Azov. Most of Ukraine's area is taken up by the steppe-like region just north of the Black Sea. Most of Ukraine consists of fertile plains (or steppes) and plateaus. In terms of land use, 58% of Ukraine is considered arable land; 2% is used for permanent crops, 13% for permanent pastures, 18% is forests and woodland, and 9% is other. Physiographic division of Ukraine Most of Ukraine consists of regular plains with the average height above sea level being . It is surrounded by mountains to its west and extreme south. Wide spaces of the country's plains are located in the south-western part of the East European Plain. The plains have numerous highlands and lowlands caused by the uneven crystallized base of the East European craton. The highlands are characterized by Precambrian basement rocks from the Ukrainian Shield. Plains are considered elevations of no more than among which there are recognized lowlands (plains) and uplands (plateaus, ridges, hill ridges).
