When a rock is disturbed, it usually contains one of the following abnormalities:
- Slanting
- Bending
- Folding
- Cracking
- Metamorphism
- or Nonconformities.
If a rock layer contains none of these, then geologists classify it as undisturbed.

How do geologist know that rock layers are undisturbed?
the way geologist know that rock layers are undisturbed is the rock layers are folded
How does a geologist know that layers are undisturbed?

How do we know if rock layers are undisturbed?
The rock layers will be easily visible.
How does a geoligist know that rock layers are undisturbed?
no because that's why I asked u
How are the layers of rock if they are undisturbed?
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.
How do a geologist use the principle of superposition?
A geologist uses the principle of superposition to determine the relative ages of rocks and sedimentary layers. This principle states that in undisturbed layers of rock, the youngest layers are at the top while the oldest layers are at the bottom. By observing the order in which different rock layers are stacked, a geologist can infer the sequence of events that happened over time in a particular location.
What is based on the idea that younger rock layers are deposited on top of older rock layers in undisturbed areas?
The answer is: Relative dating
Younger layers of undisturbed sedimentary rock are above older layers according to?
the principal of sedimentarianism
What do geologist use to match rock layers in different locations?
they lick
The statement that old rocks are on the bottom in layers of undisturbed rock is called?
principle of superposition
What is one thing that tells a geologist that rock layers have been disurbed?
If rock layers are not horizontal, then some force must have diturbed them after they were fomed.
What rock layer is the youngest?
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.
