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