Earth's Geological History and Events

The video explores Earth's history through the Geologic Time Scale, detailing the development of the scale and the major eons and eras. It covers the Hadean, Archean, Proterozoic, and Phanerozoic eons, highlighting key events like the Cambrian explosion and mass extinctions. The Paleozoic Era saw the diversification of life, ending with the Great Dying. The Mesozoic Era, known as the Age of Reptiles, ended with the K-Pg Extinction. The Cenozoic Era marks the rise of mammals and human impact on Earth.
