  1. Did you uncover the find exactly the way it was originally laid down? Explain.
    (The movement of the sand shifted some of the artifact positions)
  2. What factors affected the success of your archeological dig?
    (The amount that the sand moved, the steadiness of the brush, etc.)
  3. How might the type of soil affect your success in uncovering the artifacts?
    (Soil that doesn't shift keeps the artifacts in place)

The principle of superposition involves the relative positions of objects as they relate to the sequence of their burial. Objects that were buried first occupy a position at the bottom of the stack. Objects that were buried more recently are found at the top of the stack. Use this principle to create a top -to-bottom stack that illustrates the most likely sequence of the following objects, if they were uncovered in the same column of sediment:

  • Model T Ford
  • first living cell
  • trilobite
  • T-Rex
  • Volkswagen
  • woolly mammoth
    (Answer: Volkswagen, Model T Ford, woolly mammoth, T-Rex, trilobite, first living cell)
