Global Warming

Notes

QuestionAnswer
the effect of no greenhouse gases frigid earth
What does the atmosphere do to keep the night temperatures constant lets in the earth's solar radiation in during the day, but traps the warmth
the greenhouse gases trap heat and moisture
all energy from the sun that the earth traps radiation
when the night sky is clear what happens to the temperatures they go down
when nights are cloudy the tempeeratures do what go up because the heat is trapped
Earth's temperatures are divides into ___ layers 4
name the layers of the earth's surface outward troposphere, stratosphere, mesosphere, thermosphere
the troposphere contains: weather, breathable air, air pressure, and the majority of greenhouse gases
where do most of the greenhouse gases occur naturally troposphere
name the naturally occuring greenhouse gases: H2O, CO2, CH4, O3
name the human greenhouse gases N2O( nitrous oxide) AND SO2( sulfer dioxide)
name the gases that do not hold heat 02 AND N2
nitrogen is ___% of the atmosphere 78
Oxygen is __ % of the atmosphere 21
CO2 is __ percent of the atmosphere .03
Does CO2 hold heat yes
what would excess amount of greenhouse gases do to the earth warm to a lethal level
Venus has an atmosphere which is ____ percent CO2 and the temperature is _____ 96; 872 degrees F
what has proven the greenhouse gases and how long have they varied and what do they cause ice core samples; 800,000 years; the earth to switch between glacial periods and inter glacial periods
Within the ice samples amounts of what correlate temperature changes CO2 AND CH4
when was the paleozoic era 570 mya
during the paleozoic era the CO2 amounts were _____ times higher than present 4-6x
what helped reduce the CO2 tempertures abundant plant life
when was the mesozoic era 245 mya
during the mesozoic era the amounts of CO2 were __________ times higher than present 10- 15x
why was the climate so warm during the mesozoic era due to the increases of CO2 and this was the time the dinosaurs thrived
when did the volcanic eruptions cause the earths's CO2 level to rise and how much did it rise 550 mya; 12%
CFC stands for chlorofluorocarbon
when were the cfc's developed 1930's
Are CFC's made from fossil fuels no
what are CFC's used in refridgeration solvents and propellants in aerosol cans
what did the CFC's cause 03 depletion
what did CFC's do to be the cause of O3 depletion the cfc's got caught in the vortex and kept o3 from regenerating
During the 1970's what did countries do to try to prevent O3 depletion banned CFC's
the harmful ingredient in CFC's is chlorine
when did the world nations ban CFC's in the 1990's
what are CFC's nickname Ozone Eaters
what prevented O3 from regenerating chlorine gas
what was added to CFC's to make it non- harmful hydrogen ( now called HCFC)
What agency determines harmful pollutants Enviromental Protection Agency(EPA)
Where is the ozone layer and what does it do in the stratosphere; blocks some of the harmful radiation from the sun
how thick is the ozone 3mm
burning rays UV rays
What is the ozone layers ability breaks down gases in the atmosphere back into natural elements and compounds
Name an example of how the ozone breaks down gases CO2 + H2O = C + H = 03
What did the EPA end up doing with GFG's and when did they do this phased out all GFG's in 1992
when was the Industrial Revolution began in 1750 in England
after the Industrial Revolution what have humans been doing to harm the enviroment they have been putting more CO2 into the atmosphere than the ozone can break down
How does CO2 accumulate holds excess heat in the atmosphere
the first man made cause of global warming 1. burning of fossil fuels releases CO2 into the atmosphere and the mining of coal and oil releases trapped methane.
When did what percent of the USA emmisions come from USA 2002; 40%
2nd human cause of global warming transportation
what percent of the US CO2 emmisions come from burning gas 33%
who is the largest consumer of oil USA

2nd human cause of global warming transportation
what percent of the US CO2 emmisions come from burning gas 33%
who is the largest consumer of oil USA
Which one gives off more CO2, vehicles with poor gas mileage or a car with the average gas mileage poor gas mileage
what is the average gas mileage, and how many pounds of CO2 does this give off in the city 12 miles per gallon;800
how much CO2 do drivers in New York and Los Angeles give just sitting in their cars in traffic 600 million gallons of gas annually
