Which rock layer is the oldest?
Question
Which rock layer is the oldest?
Solution
In the study of geology, the principle of superposition is used to determine the relative ages of rock layers. According to this principle, in an undisturbed sequence of rock layers, the oldest layer is at the bottom and the layers get progressively younger as you move to the top. So, the oldest rock layer is typically the one at the bottom.
