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