An anonymous reader shares a report on The Outline: A group of geologists believe it is time to name a new continent. A paper published in the March/April edition of GSA Today, the journal for the Geological Society of America, lays out the case for Zealandia as the seventh and youngest geological continent. In the past, New Zealand was thought to be part of a collection of “islands, fragments, and slices,” the authors wrote, but it’s now understood to be part of a solid landmass. New Zealand is essentially the highest mountains of a 1.9 million square mile landmass that is 94 percent underwater, according to the paper. The authors believe it is both large and isolated enough to qualify as a continent. They note that it is elevated relative to the oceanic crust, as befits a continent, and its distinctiveness and thickness are also on par with continents one through six. What does it matter if Zealandia is officially a continent? Reclassifying the area would encourage geologists to include it in studies of comparative continental rifting and continent-ocean boundaries.
