GGR112H5 Final: GGR112 Exam Review
Document Summary
Chapter 13: weathering, karst landscapes, and mass movement. Geomorphology: the science that analyzes and describes the origin, evolution, form, classification, and spatial distribution of landforms. Denudation: a general term that refers to all processes that cause degradation of the landscape: weathering, mass movement, erosion, and transport. Differential weathering: the effect of different resistances in rock, coupled with variations in the intensity of physical and chemical weathering. Dynamic equilibrium model: the balancing act between tectonic uplift and erosion, between the resistance of crust materials and the work of denudation processes. Landscapes evidence ongoing adaptation to rock structure, climate, local relief, and elevation. Geomorphic threshold: the threshold up to which landforms change before lurching to a new set of relationships, with rapid realignments of landscape materials and slopes. Slopes: a curved, inclined surface that bounds a landform. Regolith: partially weathered rock overlying bedrock, whether residual or transported.
