Document Summary
Chapter gt: the geographer"s toolkit 8/24/2016 5:26:00 pm. [geo=earth] [graphen=to write: the study of the interdependence among geographic areas, natural systems, people and their activities over space. Geographers use maps: human geography explores human interactions spatially, physical geography explores environmental interactions. Gps: geographer"s tool: global positioning system, 24 satellites, determining location on the earth, used for navigation. Feedback systems: positive: increase temperature, more water vapor, enhances greenhouse effect, increase temperature, negative: increase temperature, more water vapor, increase number of clouds, decrease temperature. The scientific method: hypotheses: testable ideas, theories: constructed from many hypotheses that are all tested and supported by the available evidence. Any theory can fail if new data contradict it. Laws don"t explain things typically, or why, unlike theories. Remote sensing: tool for geographers and scientists: climate/weather, mapping, earth science, oceanography, geophysics, water resources and more, military applications and many more. A computer system capable of capturing, storing, analyzing and displaying geographically referenced information.
