Stratigraphy

Stratigraphy is the branch of geology that studies the sequence of sedimentary rocks and their relative position in the Earth’s crust. It provides information on the ages of rock layers, the evolution of life and landscapes, and past environmental changes. Stratigraphy involves the interpretation of rock formations and fossils to determine the relative ages of strata and reconstruct the geological history of a region. The study of stratigraphy helps geologists understand the Earth’s history, predict the presence of natural resources, and assess the potential hazards of earthquakes, landslides, and volcanic eruptions.
