Answer

Brief Explanations:

  1. Comparing ages of rocks relative to others is relative dating.
  2. Giving specific numerical ages of rocks is absolute dating.
  3. Stating one rock is younger than another is relative dating.
  4. Using radioactive material for a numerical age is absolute dating.
  5. Using index - fossils for comparison is relative dating.
  6. Giving a specific numerical age of a fossil is absolute dating.
