  1. What are the Principles that the geologist used to interpret Earth's History? Go to http://pubs.usgs.gov/gip/fossils/rocks-layers.html  http://www.columbia.edu/itc/anthropology/v1007/mack/sld001.htm  http://www.sp.uconn.edu/~geo101vc/Lecture4/sld004.htm     1.      _____________________________________________________  2.    _____________________________________________________  3.    _____________________________________________________
  2. What came first? Go to http://www.ucmp.berkeley.edu/fosrec/ScotchmoorFirst.html and complete task. Use the Geologic Time Scale to assist you in determining which came first. Go to http://www.laatlantida.net/FoGTS.html  
  3. How do we determine the relative age of the rock layers? View the outcrop figure 1 from the website http://www.ucmp.berkeley.edu/fosrec/McKinney.html . You are required to determine the relative age of the rock layers from the oldest to the youngest and if possible the relative age.

   4.   How do we determine the absolute age of the layers? Go to http://www.ucmp.berkeley.edu/fosrec/McKinney.html . Do Activity Part 2: Radiometric Dating. Read and complete activity with M & M to determine the half-life. Plot the graph and answer the questions that follow.
