| Questão | Responda |
| halocarbons | C with any of the following(can be multiple) Florine, Chlorine, Bromine, Iodine(chloroflurocarbons)(CFCs) |
| CO2 radiative forcing | 2 |
| radiative forcing CH4 | .5 |
| radiative forcing Halocarbons | .5 |
| radiative forcing N2O | .25 |
| Global Warming Potential(GWP) | sample of atmosphere add greenhouse gas and compare to present day atmosphere how to determine what GHG absorbs most |
| GWP of different GHG | CO2: 1 CH4: 84 NO2: 264 CFC(Chloro-flouro-carbons) CFC-11: 6900 CFC-12: 10,800 hydro-chloro-flouro-carbons below HCFC-21: 543 HCHC-22: 5280 |
| major C stores | Ocean-intermediate and Deep, Ocean Floor, in ocean mostly in shells, Permafrost(frozen soil specifically) |
| How long C stored in deep sea | 100-2000(deep sea) surface(1-10years) if buried >10,000years |
| how long C stored in soil | 10-500years if in vegetation(1-100years) |
| keeling curve | atmospheric carbon Dioxide has a "saw tooth pattern" because high and low depending on season(spring lower fall higher(leaves decompose)) |
| CO2 produced in soil when | dead organic matter, bacteria, oxygen |
| Co2 comes from | fossil fuel and cement, also land use changes(cutting trees) |
| 2 fossil fuels responsible for most CO2 | coal and oil |
| why increase after 1950 | population increase |
| major fuel sorces | oil, natural gas, coal, nuclear(US) China(coal, oil, natural gas) France(nuclear, oil, natural gas, coal) |
| Suess effect | decrease in C14 in the atmosphere shows that fossil fuels burning causing the increase(as fossil fuels have no C14) |
| coal produces most which type and energy | anthracite(229), heating oil(161), gasoline(157), propane(139), natural gas(117) |
| decomposing organic matter in anaerbic environment produces what | CH4(wetland, dumps, fossil fuels, biomass, ruminants(animals that eat grass type vegetation) etc. can cause anaroebic areas) |
| methane it atmosphere | converts into CO2 and H2O after around 10years |
| what manufactured products contain halocarbons | Halocarbons fire retardants(fire extinguishers), pesticide, solvents, insulation. CFS(refridge freezing(look up) |
| how do halocarbons destroy ozone | decompose into cl which destroys ozone bonding with one O and then creating oxygen and ClO |
