A) Fuel+Oxygen= Light+Heat+Carbon Dioxide+ Water Vapor
B) Fuel+Oxygen =Catalyst +CO2+Water Vapor
C) Fuel+Oxygen = Light+Heat

E) None of the answers listed

A) Tim Tebow
B) Carbon Sinks
C) The discovery of fossil fuels
D) Allowing trees to grow to maturity
E) The combustion 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) Inside all living things
C) Usually just in trees
D) Only stored in fossil fuels
E) Only in the Earth's Atmosphere

A) True
B) False

A) Both involve the transfer of materials exclusively between plants and animals
B) That cycle's crazy. Terrible. Knucklehead.
C) Both cycles stop working below freezing
D) Both involve liquid substances falling out out of the atmosphere to the Earth.
E) Both involve the transfer of materials between animals, plants and 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) Each fuel produces water vapor.
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) 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.
E) Wood produces twice as much CO2 than propane per unit burned.

A) Something that adds carbon to the Earth's crust
B) Something that adds carbon to the atmosphere.
C) Something that actively removes carbon from the Earth's atmosphere
D) None of the answers listed.
E) Something that removes carbon from the Earth's crust.

A) While coal has the greatest amount of carbon in its formula, wood produces more CO2 through combustion
B) Propane produces less Carbon Dioxide than Natural Gas/Methane when combusted
C) Propane and methane produce the same amount of C02 through combustion.
D) Paraffin has the second greatest amount of Carbon in its formula
E) Coal and oil produce the same amount of water vapor through combustion

A) The Gulf War
B) Super Bowl XLVI
C) The American Revolution
D) The Civil War
E) The Industrial Revolution

A) Tree roots put carbon dioxide back into the soil
B) All rocks absorb C02 over time
C) None of the answers listed.
D) Humans pump large amounts of C02 into large underground storage tanks called carbon sinks
E) The carbon rich bodies of animals and plants put carbon back into the Earth after they die and become buried.
