Abstract
Structure causes inequalities in the distribution of water on and just beneath the surface of the Earth's crust. As water is the prime agent of weathering and erosion this leads to unequal activity, which in turn induces reinforcement or positive feedback mechanisms. This genetically linked series of events can lead to the maintenance and enhancement of unequal weathering and erosion. Not all inequalities are directly related to structural factors but water-driven concatenations are responsible for a range of landforms. It includes rock basins, levees, and doughnuts, at one end of the scale, through corestone-boulders to karst towers and other inselbergs, and to landscapes characterized by anomalous river patterns, remnants of very old paleosurfaces, and evidence of increased relief amplitude.
