GEOG 2050 Chapter : GEOG
Document Summary
Key concepts: geography, spatial, physical geography, opened/ closed systems, feedback systems, equilibrium, scientific method, remote sensing, gps, gis. Geography: to write about the earth/ study of the earth: spatial science: how things work and relate to each other over space, geographers use maps, human geography: explores human interactions spatially, demography, econ. Geography: physical geography: environmental interactions, laws of physics, astronomy, ecology. Gps (global positioning system): used to tell where you are located on the earth- navigation: 24 satellites circle the earth. System) : used to capture, store, analyze, and display geographically referenced info (tool for geographers) Fig 1. 31- shows how gis software works: layers, bottom: survey control, soils, land cover, wetlands, floodplains, zoning, parcels, top: topographic base. Systems theory: flow of energy: sun/ solar radiation: primary source of energy. Open system: an exchange of energy with the surroundings: energy entering and leaving earth, equilibrium: input- output/ energy going in & out.
