Document Summary
Eosc 114: fragile systems learning goals: explain what density is and how it relates to stratification, explain why disaster scales are based on the. Stratification is layering of materials, where less dense materials are on top, more dense on bottom. Disasters cover a large range of damage, so to cover them all with a reasonable scale system, use ratios (order of magnitude). Intensity is inversely proportional to frequency and return period (more intense = less frequent); proportional to consequence and risk (more intense. Hurricanes sensible heat of sun evaporates water, warm air rises, accumulates in hurricane. Earthquakes after long term buildup, pe is diluted quickly into ke, heat, etc. Viscosity: how much fluid can resist changing shape, flow. = ductile; not plastic (ie. glass) = brittle. Energy conserved when it changes from form to form; natural disasters involve ke transformations. Ke of asteroid latent & sensible heat. Pe of high rocks on volcano ke while falling.
