Geological Time Scale Concepts

The video explores Earth's Geological Time Scale, detailing the four eons: Hadean, Archean, Proterozoic, and Phanerozoic. It covers significant events like the formation of the solar system, the rise of life, oxygenation of the atmosphere, and mass extinctions. The video concludes with the evolution of modern humans and the impact of these events on Earth's history.
