James looked at a picture of rock layers while studying how scientists determine the ages of rocks. He looked at the variety of layers and understood that the law of superposition indicated something about the rock layer ages. What does the law of superposition indicate? A. The rock layers can change their position and push younger rock layers under older rock layers.
B. The rock layers can change their position and push older rock layers under younger rock layers.
C. The rock layers on top are the youngest layers and the lower rock layers are the oldest layers.
