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).
