A) None of the answers listed B) Light+Heat+Fuel= Water Vapor+CO2+Catalyst C) Fuel+Oxygen= Light+Heat+Carbon Dioxide+ Water Vapor D) Fuel+Oxygen =Catalyst +CO2+Water Vapor E) Fuel+Oxygen = Light+Heat
A) Carbon Sinks B) Allowing trees to grow to maturity C) The discovery of fossil fuels D) The combustion of fossil fuels E) Tim Tebow
A) It is a reason that the carbon cycle is out of balance. B) It shows a way to store carbon C) None of the answers listed D) It is a carbon sink E) It shows atmospheric Carbon Dioxide
A) In the water molecules within our oceans. B) Only stored in fossil fuels C) Usually just in trees D) Only in the Earth's Atmosphere E) Inside all living things
A) False B) True
A) That cycle's crazy. Terrible. Knucklehead. B) Both cycles stop working below freezing C) Both involve the transfer of materials exclusively between plants and animals D) Both involve liquid substances falling out out of the atmosphere to the Earth. E) Both involve the transfer of materials between animals, plants and the earth
A) Wood produces twice as much CO2 than propane per unit burned. B) Each fuel produces water vapor. C) Because propane comes from carbon that has been stored for millions of years, it is generally considered to be a fuel that is better at balancing the carbon cycle. D) Because the trees that wood comes from are a more active part of the carbon cycle, carbon dioxide created from the combustion of wood would be less likely to contribute to long term climate change. E) Propane Propane Gas Combustion (Ethane) C3H8 + 5O2 = 3 CO2 creates fewer units of CO2 per unit of fuel combusted than paraffin Paraffin: (used in modern candles) C25H52 + 38 O2 = 25 CO2 + 26 H2O
A) Something that adds carbon to the Earth's crust B) Something that removes carbon from the Earth's atmosphere C) Something that adds carbon to the atmosphere. D) Something that removes carbon from the Earth's crust. E) None of the answers listed.
A) While coal has the greatest amount of carbon in its formula, wood produces more CO2 through combustion B) Coal and oil produce the same amount of water vapor through combustion C) Propane produces less Carbon Dioxide than Natural Gas/Methane when combusted D) Propane and methane produce the same amount of C02 through combustion. E) Paraffin has the second greatest amount of Carbon in its formula
A) Super Bowl XLVI B) The Industrial Revolution C) The Gulf War D) The American Revolution E) The Civil War
A) The carbon rich bodies of animals and plants put carbon back into the Earth after they die and become buried. B) Tree roots put carbon dioxide back into the soil C) Humans pump large amounts of C02 into large underground storage tanks called carbon sinks D) None of the answers listed. E) All rocks absorb C02 over time |
