Weathering during the Cenozoic led to the formation of an etchplain in parts of Sudetes. While this etchplain has been eroded various landforms and weathering mantles have been suggested to attest its former existence. At present the mountain range shows a remarkable diversity of landforms. Some of the landforms present are escarpments, inselbergs, bornhardts, granitic domes, tors, flared slopes and weathering pits. Various escarpments have originated from faults and may reach heights of up to 500 m. To the northeast the Sudetes is separated from the Sudetic foreland by a sharp mountain front made up of an escarpment linked to the Sudetic Marginal Fault. Near Kaczawa this escarpment reaches 80 to 120 m in height. The relative influence of Pliocene-Quaternary tectonic movements and erosion in shaping the mountain landscape may vary along the northern front of the Sudetes.
