Answer:
The law of superposition
Explanation:
The law of superposition is an axiom and a basic principle of sedimentary stratigraphy, it explains that the layers of sediment are deposited in a temporal sequence, in which the oldest are in a lower position than the most recent. Therefore, if there has been no deformation, the lower layers were deposited before the ones above, so they are older.
