Question

Which of the following could NOT be determined from using the law of superposition?

A.
That a sedimentary layer is older than the one above it
B.
That a sedimentary layer is younger than the one below it
C.
That a sedimentary layer is 100 million years old
D.
That a sedimentary layer contains fossils older than those in another layer

Answer 1

C, that a sedimentary layer is 100 million years old.

Step-by-step explanation:

The law of superposition functions without regard to exact times, basing its times relative to the layer above or below it. Without the age of a specific layer being giver in advance, you will not be able to determine the specific age of the layer being examined, only a relative age.
