Zealandia and the Concept of Continents

The video explores the concept of Zealandia, a submerged landmass in the Pacific Ocean, often compared to the mythical Atlantis. It discusses Zealandia's geological history, its separation from Gondwana, and its potential status as Earth's eighth continent. The video highlights the criteria for continent classification and the ongoing debate among geologists. It concludes with a promotion for a Skillshare class on map making.
