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.

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.

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.
