In geomorphology, badlands are areas of bare ground which have been intensely eroded by running water into a maze of miniature canyons and steep slopes. There may be hundreds of tiny stream channels within a single square kilometre or mile, with the channels containing water only after rainstorms. Common on clays and shales in areas where the climate is semi-arid, they occur also on the tip-heaps of mines, especially of china-clay workings, in areas where the climate is wetter. Resistant layers of rock are often left as cappings on pillars of softer rock; these structures are known as hoodoos, or pedestal rocks. Research Badlands
geomorphology or geomorphogeny is the branch of geology that is concerned with the structure, origin, and development of the topographical features of the earth's crust. Research Geomorphology
