Deep Time

Deep Time refers to the vast scale of Earth's history, spanning approximately 4.6 billion years. It emphasizes how Earth's events—such as the formation of continents, the evolution of life, and major climate shifts—occur over incomprehensibly long periods. This concept helps us understand that Earth's history is measured in millions or billions of years, contrasting sharply with human lifespans. Recognizing Deep Time allows scientists to study geological layers, fossils, and Earth's processes to grasp how complex life and our planet have changed gradually over billions of years.
