GEOLOGY REVIEW What is the most abundant greenhouse gas in Earth’s atmosphere? Water How old is the species Homo sapien? 200,000 yrs old The most destructive part of hurricane? Storm surge Current scientific evidence hasn’t suggested that humans evolve from monkeys Groundwater makes up about ~75 of all liquid freshwater on earth Primary source of earths oil reserves? Burial and degradation of microscopic organisms that liven in the surface Last glacial cycle? CLICKER QUESTIONS - Scientific hypotheses should always be testable - Mantle= solid; made of silicates; convects (drives plate tectonics) - During radioactive decay # parents decrease and # of daughters increase - Where would you find the oldest ocean crust? Ocean crust is formed at spreading cen youngest is at spreading centers; oldest is farthest away from spreading center - Felsic magma can be result of fractional crystallization; have high silica content; mos

Unformatted text preview: explosive; least viscous of all the magmas-Sediments carried by a high velocity stream are larger than sediments carried by stre w/ lower velocity; higher velocity streams: larger sediments (wind too)-Ripples can form in streams, deserts and beaches-Plate boundary=ductile rocks=most likely to find folds-Normal faults are associated w/ divergent boundaries-Tensional forces dominate at divergent boundaries-Best properties for an aquifer? – high porosity and high permeability-During glacial periods, earths albedo is higher: more ice, more sun is reflected-Milankovithc cycles are reflected in earths history of glaciations-Fossil fuel burning moves carbon between litho and atmosphere-Earths albedo increase, increase in amount of solar radiation increases--...
