Question

multiple-choice question
according to the law of superposition, which rock layer is the youngest?
a. the one on the bottom, because rocks like to do things backward.
b. the middle layer, because its stuck in between and needs attention.
c. the top layer, because new sediments are always deposited on top of older ones.
d. the one that looks the coolest.

Explanation:

The law of superposition is a key geological principle stating that in undisturbed sedimentary rock layers, new sediments are deposited on top of existing older layers. This means the youngest layer is the uppermost one, while deeper layers are older. Options A, B, and D provide incorrect, non-scientific reasoning.

Answer:

C. The top layer, because new sediments are always deposited on top of older ones.
