What do you think exists around the Earth’s core, just below the solid mantle layer? A team of geophysicists now has the answer
Photo: Fabio Pagani / EyeEm/Getty Images/EyeEm What do you think exists around the Earth’s core, just below the solid mantle layer? I’ll give you some time to guess. Okay. Did you say: “Large structures made of a hot, dense material ”?A team of University of Maryland geophysicists recently found evidence of these hot, dense structures, and published their findings on Thursday in the journal Science.
The “blobs” are also known as “ultralow velocity zones” because their density slows down the velocity of an earthquake’s seismic waves. The data showed the existence of a previously unknown ultralow velocity zone beneath the Marquesas Islands. It also found that the zone beneath the Hawaiian Islands is much bigger than it was previously thought to be.
“We found echoes on about 40 percent of all seismic wave paths,” the study’s co-author Vedran Lekic said. “That was surprising because we were expecting them to be rarer, and what that means is the anomalous structures at the core-mantle boundary are much more widespread than previously thought.” Will even more blobs be found around the core of our Earth? Are we walking around on blobs all day, blobs that could be magma or molten iron, or something else entirely, and we don’t even know it? Hm. It seems possible, but unless Earth whispers her secrets to us personally, I guess we’ll have to wait for the geophysicists, and the Sequencer, to find out for sure.
