Geography
Geomorphology - is the science of landforms, their origin, evolution, form, and spatial distribution.
Denudation - is any process that wears away or rearranges landforms. Processes include weathering, mass movement, erosion, transportation, and deposition.
Differential Weathering - the effect of different resistance in rock, coupled with variations in the intensity of physical and chemical weathering.
Dynamic Equilibrium Model - the balancing act between tectonic uplift and reduction rates of erosion, and between the resistance of crust materials and the work of denudation processes. Landscapes evidence ongoing adaptation to rock structure, climate, local relief, and elevation.
Endogenic Events - faulting or lava flow.
Exogenic Events - heavy rainfall or forest fire.
Geomorphic Threshold - threshold up to which landforms change before lurching into a new set of relationships, with rapid realignments of landscape materials and slopes.
Pattern Sequence Over Time: * Equilibrium stability. * Destabilizing event. * Period of adjustment. * Development of a new and different condition of equilibrium stability.
*Slow continuous events maintain an approximate equilibrium.
*Dramatic events require longer recovery times before a new equilibrium is established.
Slopes - curved, inclined surfaces that form boundaries of landforms. A slope is 'stable' is its strength exceeds denudation processes. A slope is 'unstable' if materials are weaker than denudation processes.
Weathering - rock disintegrates, dissolves, or is otherwise broken down. (physical, organic, chemical). Weathering is greatly influenced by the character of the bedrock.
Regolith - partially weathered rock overlying bedrock, whether residual or transported.
Bedrock - rock of the earth's crust that is below the soil and basically underweathered. It's the 'parent rock' from which weathered regolith and soils develop.
Sediment - fine grained mineral matter that is
