A)the first and last appearances of species in the fossil record.
B)magnetic shifts in the earth's interior.
C)radioactive decay of carbon to nitrogen.
D)the concentration of fluorine in the soil and in groundwater.

Question

Quizplus · Accepted Answer

Biostratigraphic dating determines the age of rocks by analyzing the fossil record and identifying the first and last occurrences of species. This allows scientists to correlate rock layers from different locations and determine the relative ages of geological formations. Magnetic shifts, carbon dating, and fluorine concentration are other methods of dating, but they are not used in biostratigraphy.
