Radioactive Dating Worksheet Answers This document contains a worksheet with multiple choice questions about radioactive dating The questions cover topics like half lives of different radioactive isotopes like Carbon 14 and Potassium 40 using half lives to determine the age of samples and interpreting graphs of radioactive decay
189 Life and Radioactive Decay 1 The half life of radon 222 is 4 days Using this example explain what 189 life is 2 a If you started with 100 million radioactive atoms how many would you have left after One 189 life Two 189 lives Three half lives b What happens to the radioactive atoms once they decay 3 Then answer the questions that follow on a separate sheet of paper 1 Can geologists use radioactive dating to find the absolute ages of sedimentary layers A B C D and E Explain why or why not 2 Can geologists use radioactive dating to find the absolute ages of the extrusion or the intrusion Explain why or why not 3

1 Which radioactive isotope s would be most useful in dating the age of the Earth 2 Which radioactive isotope s would be most useful in dating an ancient Egyptian artifact 3 What fraction of the original C 14 remains in a sample after 11 460 years Answers for Section H Time and the Fossil Record Absolute Dating 1 Explain how the half lives of radioactive elements are used in estimating ages of materials
1 The document provides an answer key for a relative dating worksheet with information about sequencing rock layers and applying principles of stratigraphy 2 It explains the application of principles like superposition cross cutting relationships original horizontality and lateral continuity to deduce the relative ages of rock layers 3 Radioactivity depends on the nucleus and not the atom or its chemical state Why then is one kilogram of uranium more radioactive than one kilogram of uranium hexafluoride
