What do the law of superposition and the law of inclusion have in common?

Question

A.
Both laws are about matching fossils in different areas.

B.
Both laws describe the relative ages of rocks.

C.
Both laws give the exact ages of rocks.

D.
Both laws are about the ages of intruding rocks.

Answer 1

B. Both laws describe the relative ages of rocks.

The law of superposition states that in a sequence of undisturbed sedimentary layers, the oldest layers are at the bottom and the youngest are at the top. The law of inclusion states that fragments (inclusions) within a rock are older than the rock itself. Both laws are used to determine the relative ages of geological formations.
