Ukraine is thesecond-largest European country, afterRussia. Its various regions have diverse geographic features ranging from highlands to lowlands, as well as climatic range and a wide variety in hydrography. Most of the country lies within theEast European Plain.
Lying between latitudes44° and53° N, and longitudes22° and41° E, Ukraine covers an area of 603,628 square kilometres (233,062 sq mi), with a coastline of 2,782 kilometres (1,729 mi).[1]
The total geographic area of Ukraine is 603,700 square kilometers (233,100 sq mi). Ukraine has anExclusive Economic Zone of 147,318 km2 (56,880 sq mi) in theBlack Sea.[7]
The land border of Ukraine totals 6,993 kilometers (4,345 mi).[8] The border lengths with each country are: Belarus 891 kilometers (554 mi)[failed verification], Hungary 103 kilometers (64 mi)[failed verification], Moldova 939 kilometers (583 mi)[failed verification], Poland 428 kilometers (266 mi)[failed verification], Romania 169 kilometers (105 mi) on the south and 362 kilometers (225 mi) on the west,[failed verification] Russia 1,974 kilometers (1,227 mi), and Slovakia 90 kilometers (56 mi)[failed verification]. Ukraine is also bordered by 3,783 kilometers (2,351 mi) of coastline.[failed verification] The border with Russia, part of which runs through the Sea of Azov, is the country's longest border.[9]
Relief map of UkraineSimplified depiction of thebiomes lying north of the Black Sea. The bright green belt girdling the Black Sea's southern coast, extending westwards, denotes a region ofsubtropics.
The western regions feature an alpine-like section ofCarpathian Mountains, the Eastern Carpathians that stretches across Poland, Ukraine and Romania. The highest peak isMount Hoverla, which at 2,061 meters (6,762 ft)above sea level is the highest point in the country. Mountains are limited to the west, the southern tip of Ukraine on theSea of Azov. The western region has theCarpathian Mountains, and some eroded mountains from theDonets Ridge are in the east near the Sea of Azov.
Most of Ukraine's area is taken up by thesteppe-like region just north of theBlack Sea. Most of Ukraine consists of fertile plains (orsteppes) andplateaus. 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.
Most of Ukraine consists of regular plains with an average heightabove sea level being 175 metres (574 ft). 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 theEast European Plain. The plains have numerous highlands and lowlands caused by the uneven crystallized base of theEast European craton. The highlands are characterized byPrecambrianbasement rocks from theUkrainian Shield.
Plains are considered elevations of no more than 0–600 m (0–1,969 ft) among which there are recognized lowlands (plains) and uplands (plateaus, ridges, hill ridges).
As much as two-thirds of the country's surface land consists of black earth, a resource that has made Ukraine one of the most fertile regions in the world and well known as a "breadbasket".[12] These soils may be divided into three broad groups:
in the north, a belt of deep chernozems, about 1.5 metres (5 feet) thick and rich in humus
south and east of the former, a zone of prairie, or ordinary, chernozems, which are equally rich in humus but only about 90 centimetres (3 feet) thick
the southernmost belt, which is even thinner and has still less humus
Interspersed in various uplands and along the northern and western perimeters of the deep chernozems are mixtures of gray forest soils and podzolized black-earth soils, which together occupy much of Ukraine's remaining area. All these soils are very fertile when sufficient water is available. However, their intensive cultivation, especially on steep slopes, has led to widespread soil erosion and gullying.
The smallest proportion of the soil cover consists of the chestnut soils of the southern and eastern regions. They become increasingly salinized to the south as they approach the Black Sea.[11]
Visualisation of climate change inKyiv, showing different temperature ranges between different 30-year time periods.
Ukraine is firmly in the mid-latitudes, and generally has acontinental climate, except for its southern coasts, which featurecold semi-arid andhumid subtropical climates.[18] Average annual temperatures range from 5.5–7 °C (41.9–44.6 °F) in the north, to 11–13 °C (51.8–55.4 °F) in the south.[19]Precipitation is disproportionately distributed; it is highest in the west and north and lowest in the east and southeast.[19] Western Ukraine, particularly in the Carpathian Mountains, receives around 1,200 millimetres (47.2 in) of precipitation annually, while Crimea and the coastal areas of the Black Sea receive around 400 millimetres (15.7 in).[19]
Water availability from the major river basins is expected to decrease, especially in summer. This poses risks to the agricultural sector.[20] The negative impacts ofclimate change on agriculture are mostly felt in the south of the country, which has asteppe climate. In the north, some crops may be able to benefit from a longer growing season.[21] TheWorld Bank has stated that Ukraine is highlyvulnerable to climate change.[22]
Climate data forKyiv (1991–2020, extremes 1881–present)
Ukrainehas many environmental issues.[39][40] Some regions lack adequate supplies of potable water.[41] Air and water pollution affects the country, as well as deforestation, and radiation contamination in the northeast stemming from the1986 accident at theChernobyl Nuclear Power Plant.[42]
