You might think you know all of Earth’s continents, but there’s one that has remained hidden for millions of years. Zealandia ...

As far as immutable facts go, the number of continents would seem to be one of them, but is there another continent hiding in ...

It’s also almost entirely submerged underwater and wasn’t even formally recognized as a continent until 2017. But now, it’s experiencing something of a resurgence – at least in a research ...

"We can get some very satisfying geological matches across these continents before the supercontinent broke up," said Mortimer. Under its ice, much of West Antarctica is submerged underwater ...

Some, on the other hand, actually list eight continents. This is due to the 2017 discovery of Zealandia, a small and largely underwater continent in the Southern Hemisphere (if you’ve ever been ...

Though mostly underwater, this geological giant has sparked debate as a possible eighth continent. Just 5% of its surface peeks above sea level, making it one of Earth’s most elusive landforms.

For instance, if Antarctica were ice-free, much of its western half would be underwater. What’s more, the team points out that Zealandia’s crust is indistinguishable from that of a continent’s.

They then dated the samples, interpreted their magnetic anomalies, and plotted where they were found to map the mostly-underwater continent's geography. The prevailing theory about how Zealandia ...

providing additional evidence to support the underwater continent’s discovery. A comparatively young island, Mauritius is only a few million years old–rocks that much older would have to ...
