Answer:
B. Find the relative age of one rock layer at the given location
Step-by-step explanation:
Relative age is determined by the chronological order of a sequence of events. Relative dating is based on the concept of relative age and various geological principles, such as the principle of initial or original horizontality, the principle of overlap and the principle of paleontological identity. Relative dating is therefore based on the presence of fossils in rocks and / or the relative position of geological formations.
Based on this, we can say that if a geologist wanted to determine the age of the rock layers in a given location using the relative age, he should find the relative age of a rock layer, using relative dating in the indicated location
