Geology 110

Geology Exam 3

TermDefinition
Role of exotic terranes in the evolution of western North America are volcanic island arcs/island chains/microcontinets that accreted to western North America, as opposed to big trenches and mountain chains
How the San Andreas fault system formed the result of the North American plate overriding the accent Farallon plate, as this happened transform faults offsetting segments of the East Pacific Rise linked up to produce the San Andreas fault system
Mass Extinction: Late Ordovician (causes) -giant glaciation in southern hemisphere caused sea level to decrease and cooling of the Earth -sea level regression and reduced habitat for marine life
Mass Extinction: Late Devonian (causes) -sea level increases and spread of the oxygen minimum zone into the continent (OMZ increased) -wiped out marine life
Mass Extinction: Late Permian (causes) -volcanic erruption, Siberian Traps, icrease CO2 levels, sea levels decrease -90% of creatures go extinct
Mass Extinction: Late Triassic (causes) -increased volcanism, increased CO2 levels, massive outpouring of flood basalts -gave rise to the dinosaurs
Mass Extinction: Late Cretaceous (causes) -meteor hits the Earth and spews dust back into the atmosphere blocking the sun -carbon isotopes goes down and there is less photosynthesis because of dust in clouds
Human Evolution human ancestors moved out of Africa and out of the trees as the Earth changed from forest to grassland, humans learned to walk upright, punctuated evolution of humans from primate ancestor -primates evolved stereoscopic vision (let use see in 2D & 3D)
Causes of the Younger Dryas fresh water was discharged into the North Atlantic Ocean from a glacier in Canada from Lake Agassiz
Causes of the Little Ice Age -volcanic eruptions, solar flare form the sun -ice melted from the north in to the North Atlantic Bottom Water, bringing cooler ware to Europe
Open System exchanges matter and energy with the surrounding environment
Closed System exchanges energy with the surrounding environment
Isolated System does not exchange matter or energy
Feedback a process in which information about the past or the present influences the same phenomenon in the present or future
Paleozoic orogenies of the eastern U.S. -Taconic-Late Ordovician-Taconic Mts -Acadian-Late Devonian-Catskills/Old Red Sandstone -Alleghenian-Late Paleozoic-associated with assembly of Pangea
Paleozoic orogenies of the western U.S. -Antler-Late Devonian-Nevada -Sonoma-northern California -Sevier-Colorado and areas to the north and south
Hoofed Mammal evolution Ungulates (hoofed mammal) stared out as Perissodactyls (="odd toed") that were forest animals, as the forest changed to grassland they evolved into Artiodactyls (="even toed") that were grassland animals
Horse evolution in response to climate change during the Cenozoic horses evolved from toes for running, they got larger in size, they went from browsing to grazing as the teeth changed and got bigger, eyes moved back behind the teeth, horses became herding and migratory animals
Milankovitch cycles—periodicities and causes -Eccentricity eccentricity: when the earth changes its orbit around the sun (~100,000 year to return to the same orbit)
Milankovitch cycles—periodicities and causes -obliquity obliquity: the time it take the axis of rotation to shift back to its origin position (axis shift 2-3 degrees every 20,000 years, takes ~41,000 years)
Milankovitch cycles—periodicities and causes -precession precession: means the time it takes for the seasons to cycle once (~21,000 years)
