Slide 14

Base your answer on the geologic cross section below. The large cone- shaped mountain on Earths surface is a volcano. Letters A, B, and C represent certain rocks. Which statement correctly describes the relative ages of rocks A and C and gives the best supporting evidence from the cross section? a. A is younger than C, because A is a lower sedimentary rock layer. b. A is younger than C, because the intrusion of A metamorphosed part of rock layer C. c. A is older than C, because A has older index fossils. d. A is older than C, because the intrusion of A cuts across rock layer C.
