International Stratigraphic Commission

The International Stratigraphic Commission (ISC) is a global organization that focuses on the study of Earth's layers, known as strata, which help geologists understand the planet's history. The ICS works to create standardized timelines and classifications of rock layers, helping scientists communicate findings consistently across countries and disciplines. By establishing these guidelines, the ISC aids in the identification of geological periods, making it easier to study changes in the Earth's environment, climate, and life over millions of years. Essentially, it provides a common framework for understanding the Earth's geological past.
