idk what the answer is but i chose "usually not as old as those found in deeper layers"
When archaeologists study an excavation site, objects found closer to the surface are typically more recent. This is because as time passes, layer upon layer of sediment accumulates, burying older artifacts deeper underground. So, the closer an object is found to the surface, the more likely it is to be from a more recent time period.
When archaeologists study an excavation site, objects found closer to the surface are typically more recent in age compared to objects found deeper below the surface. This is because over time, layers of soil and debris accumulate on top of older artifacts and structures, burying them deeper in the ground. As a result, archaeologists often use the principle of stratigraphy, which is the study of the sequential layering of deposits, to determine the relative age of different artifacts and features at a site.
To determine the age of objects found at different depths during an excavation, archaeologists follow a systematic process:
1. Excavation: The site is carefully excavated using a combination of shovels, trowels, and other tools. The layers of soil and debris are carefully removed to expose the artifacts and structures below.
2. Documentation: As the excavation progresses, archaeologists carefully document the location, depth, and orientation of each artifact or feature encountered. This includes taking precise measurements and recording detailed descriptions.
3. Stratigraphic Analysis: Archaeologists analyze the different layers of soil and debris encountered during the excavation. The principle of stratigraphy states that deeper layers are older than the ones above them. By studying the order and composition of these layers, archaeologists can establish a chronological sequence for the site.
4. Relative Dating: Based on the stratigraphic analysis, archaeologists can assign relative dates to the artifacts and features found at different depths. Objects found closer to the surface are generally more recent, while those found deeper are older. This technique allows archaeologists to establish a relative chronology for the site, organizing the artifacts and structures in a temporal framework.
5. Absolute Dating: In some cases, archaeologists also use absolute dating methods to assign specific numerical ages to the artifacts or features. Techniques such as radiocarbon dating, dendrochronology (tree-ring dating), and thermoluminescence dating can provide precise dates by analyzing the decay of radioactive isotopes or studying the annual growth rings of trees.
In summary, when archaeologists study an excavation site, objects found closer to the surface are typically more recent in age. This is determined through the analysis of the site's stratigraphy and the application of relative and absolute dating techniques.
