stratigraphic correlation

Stratigraphic correlation is the process of matching layers of rock and sediment from different locations based on their age, composition, and fossil content. Geologists use this technique to understand the history of the Earth and trace geological events across regions. By identifying similar layers, they can establish timelines and reconstruct past environments, helping to piece together the planet's geological history. Essentially, it’s like connecting the dots in Earth's timeline using the physical evidence found in its layers.
