Stratigraphy
Stratigraphy is the branch of geology that deals with the study of rock layers (strata) and the interpretation of their chronological sequence, distribution, and relationship to one another. It involves analyzing the composition, thickness, and arrangement of sedimentary, igneous, and metamorphic rocks in order to understand the geological history of a particular area. By examining the layers of rock, stratigraphers can reconstruct past environments, climates, and events, providing valuable insights into Earth's history and evolution.
