 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.
