A Giant Hot Blob is Heading Toward New York City—and It May Be Capable of Dividing Continents?
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.
“This thermal upwelling has long been a puzzling feature of North American geology.” lead author of the study Tom Gernon said in a press release. “Our research suggests it’s part of a much larger, slow-moving process deep underground that could potentially help explain why mountain ranges like the Appalachians are still standing.”
