the principal of sedimentarianism
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
Factors such as wind, ice, and warder contribute to sedimentary build up. As this occurs older layers of sedimentary rock are driven lower while newer layers replace them closer to the surface.
