A classification of landscape according to the processes that formed it. The footprints of wind, glaciers, climate changes and tectonic processes that shape the morphology through thousands to millions of years.

Fluvial System

From the white covers of the mountains, snow feeds rivers which are rough, straight, and rapid where the slope is steep and slow and sinuous where the slope is gentle, both kinds received by the valleys.

Rivers usually flow over beds of glacial sediments, from where they remove rock particles, from clay to pebbles, polishing, rounding, and re-organising them. While rivers excavate a fluvial valley, they leave behind terraces that record the old base of the glaciers.
