, in particular Davis' ones. Critics did however not propose alternative models. For him, the weathering of physical factors in arid areas causes the erosion of the hills, the deposition of the weathered material (pediments) and the deposition of these material in lower altitudes, contributing to the formation of the pediplain. He was also an early proponent of

continental drift Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of pla ...
