Chemistry 513 Carbon Cycle and Global Warming Research Project In what compounds/ions do we find most of the carbon in the nonliving environment? List two ways in which carbon in the nonliving environment enters the biotic world (organisms). In what ways and is carbon returned from the living (biotic) to the nonliving environment? Make a rough sketch of the carbon cycle. Your sketch must include pathway arrows to show the exchange of carbon between the biotic and abiotic environment and identify the processes by which these exchanges occur. (note: you can cut a paste a diagram from one of your references). Is the uptake and return of carbon dioxide in balance? Explain. Look up data showing how the concentration of carbon dioxide (in parts per million or ppm) at the summit of Mauna Loa in Hawaii has changed from 1958 through the present. Copy and paste the most recent graph. Based on the above graph, what causes seasonal fluctuations of the carbon dioxide levels? What is the main reason that can account for the rapid change in carbon dioxide levels and when and what started this relatively recent change? The change in carbon dioxide levels in our atmosphere is said to be “anthropogenic”. What does this mean? What are ice cores and what does the composition of air trapped in bubbles in the ice reveal about atmospheric conditions? List some ways that carbon dioxide is removed from our atmosphere (i.e. identify the sinks”) “CO2 In what way(s) may the sinks” be decreasing? “CO2 What is the Greenhouse Effect? What are the Greenhouse gases other than carbon dioxide?
