Document Summary
Please bring a small scantron form and pencil. ), location (latitude, longitude), projections (distortion, families, standard line/point); remote sensing (electromagnetic radiation, passive & active sensors, platforms, geostationary & polar orbits); geographic information systems (layers/ coverages, electronic maps). History/structure of the earth: planetesimal hypothesis; geologic time (precambrian, Phanerozoic, quaternary, pleistocene, holocene); dating (relative, superposition), (absolute, dendrochronology, radiometric, isotope, half-life); uniformitarianism, catastrophism; layers (core (inner, outer), mantle, asthenosphere, uppermost mantle, crust, lithosphere, temperature/density trends). Earth materials: element, mineral, rock; common elements; rock cycle, lithification, weathering, metamorphosis; sedimentary rocks (clastic, grain size, sandstone etc. ; chemical, evaporation, precipitation, salt, limestone; organic, coal, limestone); igneous (intrusive/extrusive, cooling rates and grain size, mafic & felsic magma, granite, basalt, intrusive formations (pluton, batholith, laccolith, sill, dike)); metamorphic (heat, pressure; contact, regional). Isostasy: vertical motions, weight, uplift (mountain erosion, ice melting), subsidence (mountain formation, erosion, ice sheet growth).
