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 Quaternary glaciations of northern Europe, on the other. Both processes shaped the Sudetes and the Carpathians. 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 Cracow-Czestochowa 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 Kraków-Czestochowa Upland is one of the oldest mountain ranges on earth.
