Stratification tells us that the closer something is to the surface, the newer it is. That means that artifacts found deep in the site are older. This helps to provide relative dating for artifacts.

Explanation:
Stratification is figuring out when sedimentary rocks layered, right? So if an artifact is stuck in one of those layers, you can find out what she the artifact is from.
