Document Summary
Equilibrium: a series of components, flows of matter and energy occur between components, much work in geomorphology uses a systems framework, feedback, a measure of the degree to which the state of a system is adjusted to its input, dependent on time scale, static equilibrium develop over steady time (very short time spans, steady state equilibrium develop over graded time intervals (decades or millennia) (cid:222, meta stable equilibrium occurs when there is a major change at a threshold. We see these layers because typically because the materials at the base were deposited first then the rest is layered on top of it and the changes in size (boundary between layers: packing, porosity, permeability. What resists the driving forces: solid earth (lithosphere, bed rock and sediments, not all material has the same resisting forces, granite has strong resisting forces, internal earth processes like volcanism, tectonics or diastrophism (cid:223) driven by the.
