    1. What role did plants play in the Great Oxidation Event?
    2. How would burial of pyrite in a sedimentary basin influence oxygen accumulation in the atmosphere?
    3. What is causing atmospheric levels of carbon dioxide, methane, and nitrous oxide to increase?
    4. Why does plant growth specifically in the Northern Hemisphere seem to have such a big impact on global carbon dioxide levels in the atmosphere?
    5. Could you apply Henry’s Law to determine whether a dissolved gas was supersaturated or undersaturated with respect to the atmosphere?
    6. How would iron reduction and sulfate reduction affect dissolved inorganic carbon speciation in water? Based on the stoichiometry of the reactions, which has the potential to have a bigger impact and why?
    7. What is soil respiration?
    8. What groups of microorganisms are capable of producing methane?
    9. Does methanotrophy occur in anoxic environments? If so, how?
    10. How might nitrous oxide be generated differently in an anoxic microenvironment with a soil compared to an oxygenated zone?
    11. If soil becomes increasingly saturated as a result of changing precipitation patterns, how would you expect the rate of organic matter degradation within the soil to change?
