Earth Minerals (rocks, minerals, soils, etc.) Natural Hazards (floods, landslides, earthquakes, volcanic activity) Land for site selection, land-use planning, enviro impact analysis Hydrologic process of ground/surface water Geologic process (deposition of sediment on the ocean floor, formation of  mountains, movement of water, etc) Human population growth     Exponential growth     : The number of people added to the population each year  isn’t constant—a constant % if the current population is added each year o Growth rate     : measure as a % o Doubling time     : time it takes for whatever is growing to double Roughly = to 70 divided by the growth rate  D=70/G Sustainability     -Development that ensures future generations will have equal access to the  resources our planet offers -Types of development that are economically viable, don’t harm the environment,  and are socially just. Earth as a System     *System: any defined part of the universe we select for study (i.e. a planet,  volcano, ocean basin, or river) Input-output analysis     : method of analyzing change in open systems Average resistance time     : Time it takes for the total stock or supply of the  material to be cycled through a system
