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) Allowing trees to grow to maturity B) Carbon Sinks C) Tim Tebow D) The combustion of fossil fuels E) The discovery of fossil fuels ![]()
A) It is carbon sink full of tree B) It is a reason that the carbon cycle is out of balance. C) It shows a way to store carbon D) None of the answers listed E) It shows a way that atmospheric Carbon Dioxide gets absorbed
A) Only in the Earth's Atmosphere B) Usually just in trees C) Inside all living things D) Only stored in fossil fuels E) In the water molecules within our oceans.
A) False B) True
A) Both involve the transfer of materials exclusively between plants and animals B) That cycle's crazy. Terrible. Knucklehead. C) Both involve the transfer of materials between animals, plants and the earth D) Both involve liquid substances falling out out of the atmosphere to the Earth. E) Both cycles stop working below freezing
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) Wood produces twice as much CO2 than propane per unit burned. C) Each fuel produces water vapor. D) 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. 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 adds carbon to the atmosphere. C) Something that adds carbon to the Earth's crust D) Something that actively removes carbon from the Earth's atmosphere E) None of the answers listed. ![]()
A) Paraffin has the second greatest amount of Carbon in its formula B) Propane produces less Carbon Dioxide than Natural Gas/Methane when combusted 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) Coal and oil produce the same amount of water vapor through combustion
A) The Gulf War B) The American Revolution C) Super Bowl XLVI D) The Civil War E) The Industrial Revolution
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) None of the answers listed. D) Tree roots put carbon dioxide back into the soil E) Humans pump large amounts of C02 into large underground storage tanks called carbon sinks |
