Document Summary
Intro: geography, human, physical, four spheres, lithosphere, hydrosphere, atmosphere, biosphere, five themes, location, place, region, movement/atmosphere, environmental impact. Methods and tools: scientific method, develop new knowledge, better approximation of reality. Methods and tools: maps, historical, a map is worth a thousand pages , ex: hurricane tracks in 1995, one-dimensional data, points, ex: locations at which the storms became strong enough to become a hurricane. Lines: pathways roads, rivers, connections, three-dimensional data, areas (polygons, regions political, climatic, choropleth map displays regions using colors, lines of different weight, etc qualitative. Isoline map divide the area into regions based on values of some data quantitative: features, scale a tool or rule that allows us to convert measurements of the map into real world equivalence, graphic scale line or bar broken into different steps. If the size of the map changes, the ratio stays the same: representative fraction can be written as a true fraction, or ration form, or verbally.
