*hazard city map reading - wed august 31st, before midnight* *catastrophes vs. disasters - friday sept 9th inclass* History of an area gives clues to potential hazards. Geologic conditions govern the type, location, and intensity of natural processes. Refers to large-scale processes that deform earths crust and produce landforms. Driven by forces within earth involves the creation, destructions, and movement of tectonic plates explains: Rocks are aggregates of one or more minerals. Rock cycle is linked to all other cycles. Water for erosion and weathering from hydrologic cycle. Solar energy drives movement of water between atmosphere and oceans and contin. Processes include: evaporation, precipitation, surface runoff, and subsurface flow. Water is stored in compartments such as oceans, atmosphere, rivers, stream, etc. Residence time is estimated average time that a drop of water spends in any compartment. Only a small amount of water is active at any given time. Transfer of chemical elements through a series of reservoirs.
