Generally speaking, the older the deeper.  If there has been very serious distortion, you can tell that from the shape of the rock layers.

If there is an igneous intrusion, we can date that very accurately (uranium-lead, potassium-argon etc), and the parent must be older than that intrusion.  If there are grains of sedimentary origin in the layer, we know that the layer must be younger than those grains.

The order of the strata was established by around 1830, and absolute dating goes back to the work of Rutherford one hundred years ago.
