sequence stratigraphy

Sequence stratigraphy is the study of how sedimentary layers (strata) are arranged and how they form in response to changes in sea levels, climate, and other environmental factors over time. It helps geologists interpret the history of Earth's surface by recognizing patterns of depositional layers arranged in repeating sequences. These sequences typically include different types of sediments and features that record rising or falling sea levels, enabling us to understand past environments and predict where valuable resources like oil and gas might be found. It’s a framework that links layered rocks to the broader history of Earth's surface changes.
