Here's a breakdown:
* Stratigraphy is a branch of geology that focuses on the study of rock layers (strata) and their relationships.
* It involves understanding the order in which layers were deposited, the time period they represent, and the processes that led to their formation.
* Artifacts found within these layers provide valuable information about past life, environments, and cultures.
Archaeology also plays a role, as it studies the human past through the analysis of material culture found in these layers.
