Ukraine is a large country in Eastern Europe, lying mostly in the East European Plain. It is the second-largest European country, after Russia. It covers an area of 603,628 square kilometres (233,062 sq mi) and with a coastline of 2,782 kilometres (1,729 mi). It lies between latitudes 44° and 53° N, and longitudes 22° and 41° E.

The landscape of Ukraine consists mostly of fertile plains (or steppes) and plateaus, crossed by rivers such as the Dnieper (Dnipro), Seversky Donets, Dniester and the Southern Bug as they flow south into the Black Sea and the smaller Sea of Azov. To the southwest, the delta of the Danube forms the border with Romania. Ukraine’s various regions have diverse geographic features ranging from the highlands to the lowlands. The country’s only mountains are the Carpathian Mountains in the west, of which the highest is the Hora Hoverla at 2,061 metres (6,762 ft), and the Crimean Mountains on Crimea, in the extreme south along the coast. However Ukraine also has a number of highland regions such as the Volyn-Podillia Upland (in the west) and the Near-Dnipro Upland (on the right bank of Dnieper); to the east there are the south-western spurs of the Central Russian Upland over which runs the border with the Russian Federation. Near the Sea of Azov can be found the Donets Ridge and the Near Azov Upland. The snow melt from the mountains feeds the rivers, and natural changes in altitude form sudden drops in elevation and give rise to waterfalls.

Significant natural resources in Ukraine include iron ore, coal, manganese, natural gas, oil, salt, sulphur, graphite, titanium, magnesium, kaolin, nickel, mercury, timber and an abundance of arable land. Despite this, the country faces a number of major environmental issues such as inadequate supplies of potable water; air- and water-pollution and deforestation, as well as radiation contamination in the north-east from the 1986 accident at the Chernobyl Nuclear Power Plant. Recycling toxic household waste is still in its infancy in Ukraine.
