6B. Plаnetаry Differentiаtiоn (15pts Tоtal, in twо parts): (Part 2 of 2) It had long been surmised that a meteor impact may have been responsible for the extinction of the dinosaurs at the end of the Mesozoic Period. However, it was not until 1980 when geologist, Walter Alvarez, discovered a sedimentary layer that was deposited at Earth's surface at approximately the same time as the dinosaurs disappeared (~65 million years ago). What was special about the layer was it contained more than 100-times the concentrations of the element Iridium (Ir) than is found in any other sedimentary rock from any time. 1. [5pts]: Use the data plot of elemental abundances in Earth’s crust (below) to explain why high concentrations of the element Iridium (Ir-spike) at the end of the Mesozoic is suggestive of a large meteor impact (think about all questions you have answered thus far on this exam).

Using concepts from this week’s material, explain two factors that would be taken into consideration when evaluating whether the officer’s use of force was reasonable.
