How can you determine the relative age of a rock layer by looking at a cross section?
In the cross section, examine the different layers. The layer at the very bottom will be the oldest, and the one above would be slightly newer, and the one above that even newer, and so on, until the most recent rock layer is found at the top. Therefore, the layer you study will depend on those features. If you know the age of one layer, you will know the relative age of another.
