Ukraine is situated in the south-eastern part of Central Europe and has its own territory, government, national emblem, flag and anthem. It borders on Russia, Byelorussia, Moldova, Slovakia, Roumania, Hungary and Poland on land and Russia, Georgia, Bulgaria, Roumania and Turkey on sea. The territory of Ukraine is mostly a level, treeless plain, calls "steppe". There are the Crimean Mountains in the Crimean peninsula and the Carpathians in the west, but they are not very high. Mixed forests of pine and fir-trees, beeches, limes, oaks and elms cover the mountains, but the thickest woods can still be found in the northern part of the republic, in Volyn. Kiev and Cherkassy lie in the midst of Ukrainian southernmost pine forest. The main Ukrainian river is the Dnieper. It is one of the longest European rivers and one of the republic's main source of hydroelectric power. The Dnieper and its tributary the Ross had been the cradle of the Ukrainian and Russian people in time immemorial. The climate of the country is moderate. Winter is rather mild, with no severe frosts but with regular snowfalls everywhere except the south. The rivers and lakes freeze in winter. The average winter temperature varies -20 Centigrade in the north to -3-5 in the south. Summer is quite hot and dry, with occasional showers and thunderstorms. The fertile black soil is well watered in spring and autumn and gets plenty of sunshine in summer. Due to favorable climatic conditions, Ukraine is traditionally an agricultural area.
