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