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