Scientists discover Earth has a hidden eighth continent

Key Points:

• Zealandia is a massive hidden landmass nearly 1.9 million square miles wide beneath the South Pacific, considered by scientists as Earth's long-lost eighth continent, with only small parts like New Zealand visible above water.
• Formed over 100 million years ago as part of the supercontinent Gondwana, Zealandia separated from West Antarctica and Australia due to tectonic movements, causing its crust to thin and sink beneath the ocean.
• New geological evidence, including rock samples dated through geochronology and magnetic data revealing volcanic activity, confirms Zealandia's continental characteristics, distinguishing it from mere oceanic fragments.
• Zealandia provides unique insights into continental evolution and tectonic plate shifts, as its submerged status has preserved geological records lost on other continents exposed above sea level.
• Despite recent discoveries, much of Zealandia remains unexplored, with future international research and advanced technologies expected to further uncover its geological history and contribution to understanding continental formation.
