The principle of superposition states that in a sequence of sedimentary rock layers, each layer is younger than the one below it and older than the one above it. In the case of the sediment core, the top represents the most recent strata while the bottom represents the time when land was first colonized by life. Therefore, the principle of superposition is necessary to properly interpret the core.
