GraceRandolph Posted 12 hours ago Posted 12 hours ago An ancient slab of Earth's crust buried deep beneath the Midwest is sucking huge swatches of present-day's North American crust down into the mantle, researchers say. The slab's pull has created giant "drips" that hang from the underside of the continent down to about 400 miles (640 kilometers) deep inside the mantle, according to a new study. These drips are located beneath an area spanning from Michigan to Nebraska and Alabama, but their presence appears to be impacting the entire continent. The dripping area looks like a large funnel, with rocks from across North America being pulled toward it horizontally before getting sucked down. As a result, large parts of North America are losing material from the underside of their crust, the researchers said. "A very broad range is experiencing some thinning," study lead author Junlin Hua, a geoscientist who conducted the research during a postdoctoral fellowship at The University of Texas (UT) at Austin, said in a statement. "Luckily, we also got the new idea about what drives this thinning," said Hua, now a professor at the University of Science and Technology of China.
