Stratigraphic Column

A stratigraphic column is a visual representation that shows how different layers of rock or sediment are arranged beneath the Earth's surface. These layers, called strata, form over time as sediments are deposited or volcanic materials settle. The column helps geologists understand the sequence, age, and environmental history of the area, revealing how the Earth's surface has changed. It’s like a timeline of geological events, with the oldest layers usually at the bottom and the newest at the top. This tool is essential for studying Earth's history, fossils, and natural resources.
