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.

Superposition can best be explained new layer on old layer?

Superposition is the theory that the rock layer that is on top is the youngest and the layer of rock on the bottom is the oldest.

Is the top layer of rock the youngest layer?

According to the Law of Superposition, in a depositional sequence of undisturbed rock layers, the top layer of rock is the most recent to form from the processes of lithification or eruption of lava onto the surface, and are therefore the youngest rock layers.

When might the youngest layer in a set of sedimentary rock not be on top?

1. If a set of rock layers has been disturbed by movement of tectonic plates, the youngest layer may no longer be on top.

Explain that folding faulting and uplifting can rearrange the rock layers so the youngest is not always found on top?

Whenfolding, faulting, and uplifting occurs, the youngest rock layer can not always be on top. With folding the oldest rock layer could get folded over on top of a younger layer. When faulting occurs a younger rock layer can become "lower" or pushed more down in the rock layers that was originally shown. When these things happen, then rock layers can become out of order and the youngest layer is not always on the top of the layer.

What layer is the youngest layer in the sedimentary rock?

How would you know which is the oldest layer in a rock?
