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