youngest, oldest

Explanation:

Three layers of strata are deposited. The law of superposition explains the age of the layers by stating that the youngest layer is on the top and the oldest layer is on the bottom.

The law of superposition is a basic law in geology which was first proposed by the Danish scientist Nicolas Steno in the late 17th century. The law of superposition explains the age of the layers of strata by stating that in a stratigraphic sequence that is left undisturbed, the youngest layer will be at the top, and the oldest layer will be at the bottom of the sequence. It means that each layer of strata is younger that the one under it, and older than the layer above it.
