Physical Geography - exam 1 notes
Ch 1.
geo = graphy =
understanding physical geography = survival!!
humans always learned their environment - adjusted - adapted
technology
pp5: areas of geography - need to specialize - employment
geography standards: 1) world in spatial terms, 2) places & regions, 3) physical systems,
4) human systems, 5) environment & society, 6) uses of geography
physical geography focuses on non-living phenomena, but...
