Geo 101  Plate Tectonics 11/09/2007 12:40:00 Review: Correlation attempts to give a continuous record for each region of the Earth  by? o Matching rocks of the same age from different locations Isotopes of an element differ by the number of neutrons in the nucleus and  are generally unstable and subject to radioactive decay. o False, number of protons not neutrons  In practice, an isotope can be used for dating samples no older than? o Six of that isotope’s half-lives The Carbon-14 method of dating can be used to date a 200,000 year-old  granite? o False, (two clues) Half-life of Carbon-14 is 5,730 years and Carbon-14  is good for dating recent samples through the atmosphere and  photosynthesis The rate of radioactive decay of isotope carbon-14 would be a good choice to  use to date which of the following items? o A Viking Longboat found off the coast of Copenhagen How old do geologists estimate the Earth is? o 4.5 Billion Years Old Notes: Why did models for the age of the Earth based on calculating heat loss give  such short ages for the age of the earth? o
