In geomorphology, the concept of the 'cycle of erosion' proposed by William Morris Davis outlines stages of landscape evolution. Which of the following landscape features is diagnostic of the 'youthful' stage of this fluvial cycle?
A. Broad alluvial floodplains with extensive meandering river channels
B. V-shaped valleys with steep gradients, rapids, and waterfalls✓ Correct Answer
C. Peneplains featuring low relief and isolated residual hills called monadnocks
D. Braided river channels flowing across wide aggradational basins
💡 Solution & Explanation
In the youthful stage of the fluvial cycle of erosion, vertical downcutting is the dominant geomorphic process, creating steep-sided V-shaped valleys, waterfalls, and rapids. Broad floodplains and meandering channels characterize maturity and old age. Peneplains with monadnocks represent the final base-level stage of erosion. Davisian geomorphology provides a foundational framework for analyzing landscape development over geologic timescales.
