After the age of catastrophic, to give strong evidence on geomorphological activities occurring on earth, he postulated that the irregular courses (symmetry and asymmetry of the valleys) of the rivers depended on the nature of rocks through which they flow. The regions of massive and resistant rocks maintain deep and narrow courses (valleys) whereas broad and meandering courses are developed in the regions of soft and less resistant rocks. Thus, this concept gives the glimpse of differential erosion.
