How do you know which layer of rock is the oldest?
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
When you have undisturbed layers of rock which is the oldest layer?
Terms in this set (14) In undisturbed horizontal sedimentary rock layers, the oldest layer is at the bottom. Each higher layer is younger than the rocks BELOW it. – Deeper you go, the older the rocks.

How layers of rocks stratified rocks are formed?
stratification (Lat.,=made in layers), layered structure formed by the deposition of sedimentary rocks. Changes between strata are interpreted as the result of fluctuations in the intensity and persistence of the depositional agent, e.g., currents, wind, or waves, or in changes in the source of the sediment.
Which type of rock is formed in layers?
Which rock layer is the youngest?
Over time, the sediments pile up to form horizontal layers of sedimentary rocks. The bottom layer of rock forms first, which means it is oldest. Each layer above that is younger, and the top layer is youngest of all.
