Sedimentary Record

The sedimentary record refers to layers of sediments, such as mud, sand, and organic material, that accumulate over time on Earth's surface. These layers preserve evidence of past environments, climate conditions, and life forms. As sediments settle and compact, they form rocks like sandstone or shale, capturing snapshots of Earth's history. Studying these layers helps scientists understand how the planet has changed over millions of years, including past climates, ocean conditions, and events like volcanic eruptions or mass extinctions. The sedimentary record is a vital tool for reconstructing Earth's geological and biological history.
