The Whole Saga of the Supercontinents

The video explores the study of natural history, focusing on Earth's constant change through continental drift and plate tectonics. It highlights Alfred Wegener's theory of continental drift and the discovery of seafloor spreading and subduction. The supercontinent cycle is explained, detailing the formation and breakup of supercontinents like Pangaea, Kenorland, and Rodinia. The video also covers major evolutionary milestones and extinction events, including the rise of dinosaurs and mammals. Finally, it predicts future continental movements and possible supercontinents, offering insights into Earth's dynamic nature.
