Answer

Brief Explanations:

  • The law of superposition states that in undisturbed rock - sequences, older rocks are at the bottom, not on top.
  • Relative position only gives relative age, not the exact age.
  • The principle of original horizontality and the law of superposition are different concepts; the former doesn't provide the basis for the latter.
  • Unconformities are breaks in the geologic record and can be used to determine relative ages of rock layers.

Answer:

Relative age can be determined by using the concept of unconformity.
