Ukraine is located in Eastern Europe and is the largest country entirely within Europe. It shares borders with seven countries: Poland, Slovakia, Hungary, Romania, Moldova, Russia, and Belarus. The country has a diverse landscape that includes plains, plateaus, and mountains, with the Carpathian Mountains in the west and the Crimean Peninsula in the south. The major river in Ukraine is the Dnieper, which flows from north to south and is vital for transportation and irrigation. Ukraine's climate is mostly temperate continental, with warm summers and cold winters. The fertile soil, known as chernozem, makes it one of the world's top agricultural producers.
