context_page_description: Poland is a country in Central Europe with an area of 312,679 square kilometres, and mostly temperate climate. with an area of 312,679 square kilometres, and a temperate seasonal climate. Situated on the North-Central European Plain, Poland's mostly flat terrain extends from the Baltic Sea in the north to the Carpathian Mountains in the south. However, within that large plain, diverse small landforms run in bands east to west.
  The Baltic coast has two natural harbors, the larger one in the Gdańsk-Gdynia region, and a smaller one near Szczecin in the far northwest. The northeastern region, also known as the Masurian Lake District with more than 2,000 lakes, is densely wooded and sparsely populated. To the south of the lake district, and across central Poland a vast region of plains extends all the way to the Sudetes on the Czech and Slovak borders southwest, and to the Carpathians on the Czech, Slovak and Ukrainian borders southeast. The central lowlands had been formed by glacial erosion in the Pleistocene ice age.
context_section_description: The geological structure of Poland has been shaped by the continental collision of Europe and Africa over the past 60 million years on the one hand and the other by the Quaternary glaciations of northern Europe. Both processes shaped the Sudetes and the Carpathian Mountains. The moraine landscape of northern Poland contains soils made up mostly of sand or loam, while the ice age river valleys of the south often contain loess. The Kraków-Częstochowa Upland, the Pieniny, and the Western Tatras consist of limestone, while the High Tatras, the Beskids, and the Karkonosze are made up mainly of granite and basalts. The Polish Jura Chain is one of the oldest mountain ranges on earth.
  Poland has 70 mountains over 2,000 metres (6,600 feet) in elevation, all in the Tatras. The Polish Tatras, which consist of the High Tatras and the Western Tatras, is the highest mountain group of Poland and of the entire Carpathian range. In the High Tatras lies Poland's highest point, the north-western summit of Rysy, 2,499 metres (8,199 ft) in elevation. At its foot lies the mountain lakes of Czarny Staw pod Rysami (Black Lake below Mount Rysy), and Morskie Oko (the Marine Eye).
  The second highest mountain group in Poland is the Beskids, whose highest peak is Babia Góra, at 1,725 metres (5,659 ft). The next highest mountain groups is the Karkonosze in the Sudetes, whose highest point is Śnieżka, at 1,603 metres (5,259 ft); Śnieżnik Mountains whose highest point is Śnieżnik, at 1,425 metres (4,675 ft).
  Tourists also frequent the Bieszczady Mountains in the far southeast of Poland, whose highest point in Poland is Tarnica, with an elevation of 1,346 metres (4,416 ft), Gorce Mountains in Gorce National Park, whose highest point is Turbacz, with elevations 1,310 metres (4,298 ft), and the Pieniny National Park in the Pieniny Mountains, whose highest point is Trzy Korony with elevations of 982 metres (3,222 ft) (the highest mountain of this range, Wysokie Skałki (Wysoka), with elevations 1,050 metres (3,445 ft), is located outside of the national park). The lowest point in Poland – at 2 metres (6.6 ft) below sea level – is at Raczki Elbląskie, near Elbląg in the Vistula Delta.
  The only desert located in Poland stretches over the Zagłębie Dąbrowskie (the Coal Fields of Dąbrowa) region. It is called the Błędów Desert, located in the Silesian Voivodeship in southern Poland. It has a total area of 32 square kilometres (12 sq mi). It is one of only five natural deserts in Europe. But also, it is the warmest desert that appears at this latitude. Błędów Desert was created thousands of years ago by a melting glacier. The specific geological structure has been of big importance. The average thickness of the sand layer is about 40 metres (131 ft), with a maximum of 70 metres (230 ft), which made the fast and deep drainage very easy.
  The Baltic Sea activity in Słowiński National Park created sand dunes which in the course of time separated the bay from the sea. As waves and wind carry sand inland the dunes slowly move, at a speed of 3 to 10 metres (9.8 to 32.8 ft) meters per year. Some dunes are quite high – up to 30 metres (98 ft). The highest peak of the park – Rowokol (115 metres or 377 feet above sea level) — is also an excellent observation point.
