Document Summary
Reflects the integration of climate, topography, tectonics, geology and biology. Dependent on the spatial distribution of each and the response (time scale) Tectonics: primary driver of landscape evolution as it sets the regional potential energy and conditions the magnitude of sediment production. Climate: primary driver of landscape evolution because climate sets the rate of sediment transfer from production to deposition zones, also conditions vegetative palette (which drives soil development) Isostasy: primary driver of landscape evolution because continues uplift after tectonics stops. Sea level: primary driver of landscape evolution as sea level is linked to global ice volume and sea level sets the base level which rivers ultimately drain. Viscous: it will flow at very small length scales. E. g. if you load up the ice mass on the mountains, the ice mass flows down the valley and builds lateral moraines. Ice volume is important in terms of global coverage.
