Geological Units

Geological units are specific layers or parts of Earth's crust that contain distinct types of rocks, fossils, or features. They help geologists classify and understand the Earth's history by grouping together similar rock formations or deposits from particular periods. These units are standardized, so scientists worldwide can communicate about the same rocks or layers accurately. Think of them as chapters in Earth's story, each providing clues about the planet's past environments, climate, and life. By studying these units, we gain insights into Earth's development over millions of years.
