Answer 1

When archaeologists study an excavation site, objects found closer to the surface are often D) usually not as old as those found in deep layers. This is because, generally, sediment layers accumulate over time, so the deeper you go, the older the artifacts are likely to be. Excavation sites typically follow the principle of stratigraphy, where lower layers are older than upper layers due to the natural processes of deposition.
