GEO-200: Earth Science (Wk. 1) earth science is not just rocks!! *uriting intensive credit The earth is: -a complex system -Constantly charging & renewing itself Sperial Place Project due Fridery (1/22) Xquizzes are open took Ged to krew) GEO-241: Earth Science Laboratory Quartz Luster Streak Colar Hardness GEU-200: Week 2 ว Minzims Elements Grovips -alkali & altraline earth metals (lose elections to become casticad - transition metals -semi-melals -nonmetals - halides (gain electrons to become anions). -noble gases (do not rend). Elements in the Geesphere. -hydrogen -carbon -oxygen -fluorine - sodinam -magnesium -aluminnes mineral-a solid, inorganic, crystalline, compound of one or more elements. Salid natural •chemically composed generally inorganic crystalline structure Week 6, Day 3 hot spot-where mantle plumes are found(?) divergent rift valley-where a convergent boundary splits apart (splits the crust) continental rifting (divergent boundaries)-continent splits & an orean fotms •rift vealley forms at the bottom of the cezar subduction-occurs of a convergent plate boundary •also forms volcanoes Roceanic crust is generally younger than continental crust 2/19/24 Weck 7, Day 1 Continental Drift (langaen splitting apart) *90%. of paithapotes oceri plate boundarier Evidence: -similemcity at lossils -end & lucks & landleims Alus of the sees accur@plate boundariest S-warts -secondary ware -slower than p-waves -solids unty (unced hand the tants Weck 7, Day 1 (cont) Seismograph-a recording -Pwares on deserved filst, then 5 waves - then surface waves 15 wave usually appeats 11 nin after 1st P wave Richler scale-measures the distance, magnitude & amplitude of an earthquate 2/21/24 Weck 7, Day 2-Tsunami Charaderistics. Liquefaction-produces quick sand 1) displuce the sea floor -fault must move vertically -subduction zone/trench Waves during a tsunami slow down 2) length decreases 3) height builds Volcances Every volcano is different. Volcanoes are found in -subduction zones (convergent plate boundaries) -spreading centers(divergent plate boundaries) period-time letween wave erests generally 10-60 min I this does not apply to a tsunami
