The correct answer is D. Superimposed.
Ages of rock formations can be superimposed to determine their relative age. This involves analyzing the layering and order of rocks in a given area to determine which layers are older or younger than others. The principle of superposition states that in an undisturbed sequence of rock layers, the oldest layers are at the bottom and the youngest layers are at the top. By analyzing the position of different rock layers in relation to one another, geologists can establish the relative ages of those rocks.
