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