bio final exam

bio final exam (chapter 9)

Dr Sam's Favorite phytoplankton; bottom of the food chain cocolithophore
what creates phytoplankton? CO2
common uses of CO2 dry ice, fire extinguishers, soda
some air pollutants methane,hydrogen sulfide, phosphoric acid, carbon dioxide
overall temperature with massive and permanent ramifications climate change
how is clean, dry air divided? mostly nitrogen and oxygen; a little argon, CO2, water vapor, and aerosols
minute particles and liquid droplets suspended into the air aerosols
varies in thickness, 5 miles thick at equator, 75% of the mass of the atmosphere, energy gets redistributed by convection currents troposphere
little to no water vapor, 1000 times more ozone than troposphere stratosphere
levels of atmosphere? thermosphere, mesosphere, stratosphere, and troposphere (very clear boundaries
explain the greenhouse effect absorbed energy is gradually re-emitted as lower quality heat energy
how did the process get the name greenhouse effect? the atmosphere transmits sunlight while trapping heat, much like a greenhouse
a huge amount of stored energy contained in water vapor latent heat
what is another name for Deuterium? heavy hydrogen
forms of a single element that differ in atomic mass due to a different number of neutrons in the nucleus isotopes
what causes catastrophic climate swings? milankovitch cycles
periodic shifts in the earth's orbit and tilt milankovitch cycles
who are milankovitch cyles named after? Serbian scientist Milutin Milankovitch
what country gives of the lowest emissions of greenhouse? Chad
name 3 types of evidence scientists have on climate change permafrost is melting (never happened before); arctic sea is only half as thick as it was 30 years ago; Alpine glaciers are retreating rapidly
the level of ice underground that supports things like houses, roads, pipelines, and sewage systems permafrost
the height of the seas with respect to a land benchmark, averaged over a period of time local mean sea level
how high has the LMSL risen in the last 50 years 4 inches
a potentially endangered species living in the circumpolar north, on the arctic sea polar bears
how do polar bears capture seals with the help of the ice? the breaks in the ice make it easier for polar bears to determine where seals will surface for air
what species may boom if global warming increases? insect species living in warmer areas due to higher metabolic rates and more reproduction
4 key elements to combat climate change emissions trading, technology sharing, reduce deforestation, helping poorer countries to adapt
this treaty sets different limits for individual nations, depending on their output before 1990 kyoto protocol
3 ways to control greenhouse emissions double fuel economy from 30 mpg to 60 mpg; cut average travel per car from 10,000 to 5,000 miles; update all building insulation, windows, and weather stripping to modern standards
consequences for breathing dirty air? increased probability of heart attacks, respiratory diseases, and lung cancer
the injury caused by exposure to two factors together is more than the sum of exposure to each factor individually synergistic effects
effects of air pollution plants are sensitive to pollutants, smog and haze reduce visibility, acid deposition
the deposition of wet, acidic solutions or dry, acidic particles from the air acid precipitation
