Exploring Super-Continents Before Pangea

The video explores the history of Earth's continents, starting with Alfred Wegener's theory of continental drift. It discusses early supercontinents like Valara, Ur, and Columbia, and their influence on modern geography. The video covers Rodinia's formation and its role in triggering Snowball Earth, a global ice age. It then examines Gondwana and Laurasia, leading to the formation of Pangaea. Finally, it details the breakup of Pangaea, resulting in the continents we know today.
