Geoarchaeology is an interdisciplinary field that combines principles of geology and archaeology to study the relationship between human activity and the Earth's physical environment. By analyzing soil, sediments, and landforms, geoarchaeologists can uncover how ancient people interacted with their surroundings, including how they adapted to climate changes and utilized natural resources. This field often involves techniques such as stratigraphy, which examines layers of soil, and geospatial analysis, which maps archaeological sites in relation to geological features. Through these methods, geoarchaeologists can provide insights into past human behaviors, settlement patterns, and the impact of environmental changes on societies.
