Once again, we request your assistance in determining the most effective dating technique to be used to calculate the age of these two objects. We need your help in selecting the best elemental isotope to be used Radioactive dating review and reinforce answers to impossible quiz the radioactive dating process.
An obsidian hand-axe said to have been discovered in Ethiopia. Obsidian is a special type of igneous rock that can have very sharp edges. The person who discovered it claims it was crafted by an Australopithecus afarensisan ancient ancestor of modern humans, sometime in Radioactive dating review and reinforce answers to impossible quiz late Pliocene or early Pleistocene.
However, to this date, no evidence has ever been presented that Australopithecus afarensis was able to craft such tools. If this rock formed less than 2 million years ago, then it is impossible that it was crafted by an Australopithecus! However, if it is older, this discovery could open an exciting new chapter in the history of human tool use! A sedimentary rock specimen pulled from a layer of stone discovered in central Australia.
This rock may provide proof of an ancient sea that once covered the middle of the continent. Fossil
Radioactive dating review and reinforce answers to impossible quiz, turtles, and plesiosaurs nearby suggest this sedimentary rock was formed during the Cretaceous period, just before the dinosaurs went extinct. Please write us back and tell us which elemental isotope you feel should be used to calculate the age of each of these latest specimens and the procedure you used to arrive at these conclusions.
Please explain why you selected that particular elemental isotope for each specimen with clear and concise reasoning. Note that this is the same data set as used in the first section. In the second part of the lesson, the data remains the same and is instead used to analyze two new items. Be sure students have access to a simple geologic time scale. This image was acquired at GreenForecast. As indicated in the Instructional Suggestions section above, this lesson allows for a 60 minute time extension to be completed in 2 full blocks if needed due to any modifications or accommodations your students may require.
