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