You can tell the age of the layers. The bottom layer is the oldest and the top is the youngest. When the layers are disturbed they tend to get bent and messed up and you cannot tell the age
the way geologist know that rock layers are undisturbed is the rock layers are folded
the principal of sedimentarianism
no because that's why I asked u
When a rock is disturbed, it usually contains one of the following abnormalities:SlantingBendingFoldingCrackingMetamorphismor Nonconformities.If a rock layer contains none of these, then geologists classify it as undisturbed.
principle of superposition

The rock layers will be easily visible.
The undisturbed rock layers are horizontal and in order of age from youngest nearest the surface to oldest at the bottom of the rock unit.
The answer is: Relative dating
That would depend on the meaning of 'undisturbed'.
the principal of sedimentarianism
When you look at a rock that has undisturbed layers, the bottom layers are older and the upper layers are younger. Anytime a rock layer crosses another (ie. an intrusion), the crossing layer is younger.

principle of superposition
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.
