soil stratigraphy

Soil stratigraphy is the study of layers (strata) of soil and sediment that accumulate over time. Each layer represents a different period of deposition, revealing the area's geological and environmental history. By examining these layers, scientists can understand past climates, natural events, and human activities. The layers are usually distinguished by differences in composition, color, texture, and other features. Soil stratigraphy is important in fields like archaeology, geology, and environmental science, helping to interpret the Earth's past and assess conditions for construction, farming, and conservation efforts.
