Question

Which relative dating principle states that sedimentary layers lower in a sequence are older than the sedimentary layers on top of (or overlying) them?

Answer 1

The principle of superposition

Step-by-step explanation:

The principle of superposition states that sedimentary layers are deposited in sequence, and, unless the entire sequence has been turned over by tectonic processes or disrupted by faulting, the layers at the bottom are older than those at the top.
