A) None of the answers listed B) Light+Heat+Fuel= Water Vapor+CO2+Catalyst C) Fuel+Oxygen =Catalyst +CO2+Water Vapor D) Fuel+Oxygen= Light+Heat+Carbon Dioxide+ Water Vapor E) Fuel+Oxygen = Light+Heat
A) Allowing trees to grow to maturity B) The combustion of fossil fuels C) Tim Tebow D) The discovery of fossil fuels E) Carbon Sinks
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) Only stored in fossil fuels B) Inside all living things C) In the water molecules within our oceans. D) Usually just in trees E) Only in the Earth's Atmosphere
A) False B) True
A) Both involve liquid substances falling out out of the atmosphere to the Earth. B) Both cycles stop working below freezing C) Both involve the transfer of materials exclusively between plants and animals D) Both involve the transfer of materials between animals, plants and the earth E) That cycle's crazy. Terrible. Knucklehead.
A) 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. B) Each fuel produces water vapor. C) Wood produces twice as much CO2 than propane per unit burned. D) 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 E) 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.
A) Something that removes carbon from the Earth's crust. B) None of the answers listed. C) Something that adds carbon to the atmosphere. D) Something that removes carbon from the Earth's atmosphere E) Something that adds carbon to the Earth's crust
A) Propane and methane produce the same amount of C02 through combustion. B) Paraffin has the second greatest amount of Carbon in its formula C) Coal and oil produce the same amount of water vapor through combustion D) Propane produces less Carbon Dioxide than Natural Gas/Methane when combusted E) While coal has the greatest amount of carbon in its formula, wood produces more CO2 through combustion
A) Super Bowl XLVI B) The Gulf War C) The Industrial Revolution D) The American Revolution E) The Civil War
A) Tree roots put carbon dioxide back into the soil B) The carbon rich bodies of animals and plants put carbon back into the Earth after they die and become buried. 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 |
