Climate as a Primary Driver of Geomorphic Processes

Climate influences landform evolution the intensity and type of weathering, erosion, and deposition. Indirectly, climate shapes vegetation cover, soil development, and hydrological regimes, which in turn modulte geomorphic processes. Thee following sections break down these fundemental interactions.
