5. The statement that in undisturbed sedimentary rock layers, older layers of rock lie under younger rock layers is the
A. Theory of plate tectonics
B. Geological time scale
C. Law of superposition
D. Process of natural selection

The correct answer is - option C. Law of superposition.

Explanation:

According to the law of superposition states that within a sequence of layers of natural sedimentary rock without any disturbance, the oldest layer is lies under the younger layers with ascending order in the sequence.

If a sedimentary rock has 4 layers as a, b, c and d where the younger layer d would be on top and the oldest layer a would be at the bottoms.

Thus, the correct answer is - option C.

C.Law of superposition

Explanation:

C is the correct answer because it is the law of superposition

the answer is true.
