None of the following is settled by relative dating alone except

  • A.the order in which two beds were laid down
  • B.the age of a bed in millions of years
  • C.the rate at which a bed accumulated
  • D.the absolute duration of a geological period

Answer: A

Correct answer: the order in which two beds were laid down

Order is exactly what relative dating gives, and it does so securely from superposition and cross-cutting relationships. Ages in years, rates of accumulation and the duration of a period all require numbers, and numbers require radiometric or other absolute methods.
