A giant hot blob, known as the Northern Appalachian Anomaly (NAA), is moving towards New York City. This blob is believed to have caused the split between Canada and Greenland 80 million years ago, and its movement could have significant implications for the continent’s geology.
The theory of continental drift was proposed by German meteorologist Alfred Wegener more than a century ago in 1912. According to the theory, the continents we know today were once connected as one big “supercontinent” called Pangea. The theory explains why continental coasts align like puzzle pieces, and why fossils from certain species are found in vastly different places.
Experts suggest that the supercontinent began breaking apart around 200 million years ago—a timeline that has been widely accepted as geological history for decades. But an international research team may be challenging that notion. A new study published in the journal Geology suggests that a giant, hot blob split Greenland from North America 80 million years ago—and now, it’s heading toward New York City.
Using geodynamic simulations, tectonic plate reconstructions, and seismic tomography data, researchers traced the origins of the mass back to the Labrador Sea, where Canada and Greenland began splitting around 80 million years ago. Researchers estimate that the blob migrates at a rate of 20 kilometers (12 miles) per million years. Per the team’s calculations, the mass is steadily heading toward New York City—but Yankees fans, fear not! Experts anticipate the center of the anomaly won’t pass through the Big Apple for the next 15 trillion years.
What Does This Mean for the Continent’s Geology?
The study expands on recent research that proposed a new idea called the “mantle wave” theory, which posits that the molten material beneath Earth’s surface behaves almost like a lava lamp. When continents divide, hot, dense rock bubbles off the base of tectonic plates, and the “waves” move across continents’ lower surfaces. Once beneath the base of a continent, the heat from the blob works like the fire in a hot air balloon, making the continent more buoyant.
Needless to say, this is certainly an example of “slow and steady wins the race”—at least when it comes to forming the continents. According to lead author Tom Gernon, there is still a lot to learn about how the continents came to be arranged in the way we see them today.
“Even though the surface shows little sign of ongoing tectonics, deep below, the consequences of ancient rifting are still playing out,” he explained in a press release. “The legacy of continental breakup on other parts of the Earth system may well be far more pervasive and long-lived than we previously realised.”
Conclusion
The discovery of the giant hot blob and its potential impact on the continent’s geology is a significant finding that sheds new light on the Earth’s history. As researchers continue to study this phenomenon, we may uncover even more secrets about the Earth’s formation and evolution.
