Step-by-step explanation:
The steps to unearth remains and preserve all evidence in archaeology include conducting a survey to locate artifacts, dividing the site into sections using a grid system, carefully excavating the site, documenting and mapping artifacts and features, and cataloguing and recording the items found. Excavation techniques vary depending on the fragility of the artifacts, and soil samples may be collected for further analysis. The goal is to leave artifacts in situ, or in their original place, to provide context and insight.
