How Does Stratigraphy Help Understand The Geological Time Scale? Have you ever wondered how scientists piece together Earth's history from millions of years ago? In this engaging video, we explore how the study of rock layers reveals the story of our planet’s past. We’ll explain key concepts like the law of superposition, which helps determine the relative ages of rock layers, and the principle of faunal succession, which shows how fossils appear in a predictable order across different regions.

You’ll learn how specific layers mark important periods in Earth's history, such as mass extinctions, and how gaps in the rock record, known as unconformities, indicate periods of erosion or non-deposition. We’ll also look at how all these principles combine to form a stratigraphic column—a visual timeline of Earth's geological history—used by museums to educate visitors about Earth's changing environments and life forms over millions of years.

Discover how stratigraphy connects local rock formations to global events, helping scientists understand major shifts in Earth's history, from volcanic eruptions to asteroid impacts. This video offers a clear overview of how the layers of rocks serve as a timeline that makes the vast history of our planet accessible and understandable.
