The bottom is oldest.
The top is newest.
-From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.

∙ 11y agoThe principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.
principle of superposition
According to the Law of Superposition, any sequence of rocks in layers, undisturbed, youngest on top, oldest at bottom
The chronological order of rock layers is usually determined by their order in an undisturbed sequence of strata. According to the principle of superposition, the oldest layers would be found at the bottom and the youngest layers at the top. In disturbed rock layers (those that have been folded, uplifted, or generally disrupted by tectonic forces), the determination must be made based on the presence of index fossils, comparison to undisturbed strata or radiometric dating.
The bottom layer of rock in a geologic sequence is usually called the basement layer.

That the youngest rock is on top while the oldest is at the bottom
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.

In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
