Marine Sediment Core

A marine sediment core is a long cylinder of mud, sand, and organic material drilled from the ocean floor. Scientists extract these cores to study layers of sediment accumulated over thousands to millions of years. Each layer contains information about Earth's past climate, ocean conditions, and biological activity. By analyzing these layers, researchers can reconstruct historical environmental changes, gain insights into climate cycles, and understand how the oceans and climate have evolved over time. Sediment cores are essential tools for studying Earth's history and informing predictions about future environmental trends.
