Which of these statements best describes the law of superposition?
A) Sediments will be deposited in horizontal layers.
B) In any undisturbed sedimentary deposits, each layer is younger than the layer beneath it.
C) In any undisturbed sedimentary deposits, each layer is older than the layer beneath it.
D) The uppermost sediments are the most important for archaeological analysis.

Question

Quizplus · Accepted Answer

The law of superposition states that in any undisturbed sedimentary deposit, each layer is younger than the layer beneath it. This means that the oldest layers are at the bottom and the youngest are at the top. This is a useful principle for determining the relative age of different layers in a rock formation or for archaeological analysis. Choice A is incorrect because sediments can be deposited in different orientations, not just horizontally. Choice C is the opposite of the law of superposition. Choice D is not directly related to the law of superposition.
