(Business Insider) Kids are frequently taught that seven continents exist: Africa, Asia, Antarctica, Australia, Europe, North America, and South America.
Geologists, who look at the rocks (and tend to ignore the humans), group Europe and Asia into a supercontinent — Eurasia — making for a total of six geologic continents.
But according to a new study of Earth’s crust, there’s a seventh geologic continent called “Zealandia,” and it has been hiding under our figurative noses for millennia.
The 11 researchers behind the study say that New Zealand and New Caledonia aren’t merely island chains. Instead, they’re both part of a single, 4.9 million-square-kilometer (1.89 million-square-mile) slab of continental crust that’s distinct from Australia.
