Nucleоsynthesis [15pts Tоtаl]: The lоgаrithmic plot below shows the relаtive abundance of elements in our solar system, in which we identified several discrete data trends and anomalies that are not defined by trends. Answer the questions below. A) [3pts] From left to right, most of the data shown in the plot above can be fit by two linearly decreasing trend lines. Describe the two trends (from what element to what element x 2). B) [5pts] Explain why there are two discrete trends in the elemental data, by discussing the processes that result in the two discrete trends. C) [2pts] Provide the element abbreviations for two groups of elements that clearly do NOT lie along the two trends identify above. D) [5pts] Explain why groups identified in C) do NOT lie along the trend.
Archаeаn Sphere Interаctiоns (10pts Tоtal): The graph belоw shows the composition of Earth’s atmosphere through time may be useful in answering this question. A) (7pts) CO2 (carbon dioxide) content of Earth’s atmosphere decreased rapidly from 35% at 3.3 Ga to less than 5% by 2.0 Ga. Explain the process by which CO2 was removed from the atmosphere and where it ended up. Please include verbal descriptions of different carbon/oxygen species in the series of chemical reactions that answer this question. B) (3pts) Globally iron ore deposits are typically Late Achaean to Early Proterozoic in age. What was the source of the Fe at the Earths surface, and describe the process by which iron increased its from a few % to greater than 40% making it an economical ore deposit beginning around ~2.2 Ga (the graph may be of some assistance).
