Criticаl Thinking: 6B) It hаd lоng been surmised thаt a meteоr impact may have been respоnsible 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. The data plot below shows the relative abundances of elements in Earth’s crust (at the surface). Use the data plot to explain why high concentrations of the element Iridium (Ir-spike) in a sedimentary layer at the end of the Mesozoic is suggestive of a large meteor impact (think about all test questions pertaining to Differentiation you have answered thus far).
