GGR112H5 Study Guide - Final Guide: Decibel Watt, Weathered, Ice Shelf
Document Summary
Chapter 13: weathering, karst landscapes and mass movement. Geomorphology: the science that analyzes and describes the origin, evolution, form, and spatial distribution of landforms. Exogenic system: powered by solar energy and gravity, wears down landscape through processes of landmass denudation. Landmass denudation includes: weathering, mass movement, erosion, transportation, deposition. Different rocks offer different resistance to weathering processes and produce a pattern on the landscape of differential weathering. Agents of change include moving air, water, waves and ice. Since the 1960"s, research and understanding of the processes of denudation have moved towards the dynamic equilibrium model. Dynamic equilibrium model: considers the slope and landform stability to be consequences of the resistance of rock materials to the attack of denudation processes. Illustrate the forces at work on materials residing on a slope: Slopes are shaped by the relation between: rate of weathering and breakup of slope materials, rate of mass movement and erosion of those materials.
