LATEST VERIFIED UPDATE: ESS 101 A+ QUESTIONS AND ANSWERS. choose magma for Cascades, Philippines, Japan, Mt. Rainier, Andes, Mt. Fuji andesite choose magma type for plutons under the himalayas, Sierra Nevada, Ural Mts. Appalachian granite choose magma type for Colombia Plateau, Iceland, Jaun De Fuca, yellowstone basalt aestheonsphere is composed of rock rich peroditite as granitic magma rises melting temp. increases and it crystallizes partial melt of aesthenosphere rises b/c melt is less dense than surrounding rock pillow basalts form basalt flow erupts into water type of margin when Appalachian Mts. formed collision margin volcanic rock that incorporates lithic fragment volcanic breccia quartz develops 6 cleavage planes SIKE...there are no cleavage planes diamond is harder than granite b/c diamond has covalent bonds, granite has vanderwahl bonds andesitic rocks usually porphyritic b/c 2 staged cooling process magnetic minerals crystallizes form an igneous melt today will... all point to a common pole AND have similar polarity SiO4 charge -4 how does SiO4 balance share w/ O2, form metallic/ionic bonds with cations terrestrial planets have so little hydrogen b/c terrestrial planets are so close to the sun that the low density hydrogen dissolves how many oxygen atoms are being shared between the silicate tetrahedral muscovite bond 3 muscovite cleaves between its silicate sheets the bonds are stronger w/in the sheets than between the sheets why is OH so important in the muscovite crystal structure its water that is incorporated in the subduction process low velocity zone of the earth is asthenosphere meteorites are composed of... similar minerals that are in solid earth (iron-nickel and silicate) topographic expression of hawaii decreasing to the big island b/c ocean lithosphere is lighter plate margin by the Andes convergent margin (ocean-continent) do smaller molecules have stronger vanderwahl forces? #ornah magma type Sierra Nevada batholith granite magma type for phillipine islands andesite Colombia Plateau is composed of rock rich in basalt melting temp. of granitic magma increases as pressure is reduced partial melt of the asthenosphere will not rise to the surface b/c Not a valid question Aa basalts blocky textured flows form as viscosity increases two ocean plates converge the older plate seducts explanation for earths magnetic field movement of electrons, outer core plate margin in E. Africa divergent margin type of volcanic rock that incorporates lithic fragments during an eruption volcanic tuff potassium feldpar develops cleavage planes b/c this mineral has an aluminum atom mount vesuvius pyroclastic magnetic minerals that crystalize in N.. Pole be oriented perpendicular weakest chemical bond Vanderwahl strongest chemical bond covalent common elements in rocks in crust/mantle silicon and oxygen why do large jovian planets have molecular H in their atmospheres Jovian planets are farther away from the sun than terrestrial planets most mined iron ore oxide lead, silver and copper occur sulfide densest compositional zone inner core least dense compositional zone continental crust tectonic setting at Yellowstone hotspot seismic waves decelerate in the low velocity zone b/c low-velocity zone is at the pressure melting temp. for the earths mantle cause of volcanism observed in cascades is similar to Phillipines, Japan, Andes during diff. of the earth into its comp. zones, heat is generated from radioactive heating, kinetic energy, compressional heating Colorado Plateau and rifting of Nevada and Utah spreading ridge in California transform plate boundaries are ass. w/ divergent margin, rate of spreading is diff. shield volcano lower slope than start volcano b/c basaltic lava flows, lower viscosities Hawaii islands and emperor seamount tectonic plate tectonic margin w/ only shallow focused divergent AND transform basaltic composition magma all of the above
