Stratigraphy - English Definition & Meaning

Definition

Stratigraphy is the branch of geology that studies rock layers (strata) and layering. 🪨 It's like reading the Earth's history book, page by page. Stratigraphers analyze the composition, sequence, and age of rock layers to understand past environments, geological events, and the evolution of life. They also use fossils found in the strata to date the layers. Think of it as being a geological detective. Unlike other geologic fields, stratigraphy deals with sequenced rock layers and their significance. 🔍

Etymology

The word "stratigraphy" comes from the Latin word "stratum," meaning "layer," and the Greek word "graphia," meaning "writing" or "description." So, stratigraphy literally translates to the description of layers. This directly reflects its focus on the study of layered rocks.
