Silesian Upland in the context of "Highland (geography)"

Silesian Voivodeship (Polish: województwo śląskie [vɔjɛˈvut͡stfɔ ˈɕlɔ̃skʲɛ] ) is an administrative province in southern Poland. With over 4.2 million residents and an area of 12,300 square kilometers, it is the second-most populous, and the most-densely populated and most-urbanized region of Poland. It generates 11.9% of Polish GDP and is characterized by a high life satisfaction, low income inequalities, and high wages.

The region has a diversified geography. The Beskid Mountains cover most of the southern part of the voivodeship, with the highest peak of Pilsko on the Polish-Slovakian border reaching 1,534 m (5,033 ft) above sea level. Silesian Upland dominates the central part of the region, while the hilly, limestone Polish Jura closes it from the northeast. Katowice urban area, located in the central part of the region, is the second most-populous urban area in Poland after Warsaw, with 2.2 million people, and one of Poland's seven supra-regional metropolises, while Rybnik, Bielsko-Biała and Częstochowa and their respective urban areas are classified among the country's 15 regional agglomerations.

The Kraków-Częstochowa Upland, also known as the Polish Jurassic Highland or Polish Jura (Polish: Jura Krakowsko-Częstochowska), is part of the Jurassic System of south–central Poland, stretching between the cities of Kraków, Częstochowa and Wieluń. The Polish Jura borders the Lesser Polish Upland to the north and east, the foothills of the Western Carpathians to the south and Silesian Upland to the west.

The Polish Jura consists of a hilly landscape with Jurassic limestone rocks, cliffs, valleys and vast limestone formations, featuring some 220 caves. The relief of the upland developed since the Paleogene, under climatic conditions changing considerably. Its main component is a peneplain, crowned by monadnocks, rocky masses that resisted erosion, generated as hard rock on Late Jurassic buildup surrounded by less resistant bedded limestone of the same age. The Polish Jura is visited by roughly 400,000 visitors a year. Part of it belongs to the Ojców National Park, the smallest of Poland's twenty national parks, ranking among the most attractive recreational areas of the country.
