Mountains Bigger Than Everest Inside Earth’s Mantle.

“They are among the largest things inside the Earth, and yet we literally do not know what they are, where they came from, how long they’ve been around, or what they do.”

March 18, 2019 Albuquerque, New Mexico –  At the end of February 2019, the geology and geophysics journal EOS headlined, “The Unsolved Mystery of the Earth Blobs.”

Back in the 1970s, scientists were puzzled when seismic tomography showed that waves from some deep earthquakes traveled more slowly from huge regions nearly half way to the center of the Earth’s mantle that surrounds the iron crystal core.

Most people have pictures in their head from school of a smooth red ball representing the Earth’s iron core surrounded by another thick orange spherical layer that represents the hot magma extending from the Earth’s core to the surface.

Mountainous “Blobs” On Outer Mantle Core Are Higher Than Mt. Everest 

But today geophysicsts know that those neat spherical layers are not a true picture of what’s inside our planet. In the recent EOS report on February 27th, 2019, new computer models show two massive mountainous regions the length of whole continents that rise up 100 times higher than Mount Everest. Everest is 29,000 feet high, or 5.5 miles. So 100 times that height is 2,900,000 feet — and that is 549 mile-high-mountainous blobs that rise up from the bottom of Earth’s rocky mantle above the molten outer core. If the mountainous blobs were placed on the Earth’s surface, they are so large that the International Space Station, 240 miles above us, would need to navigate around the mountainous blobs.

Where Are the Blobs and What Are They Made Of?

Where are the mountainous blobs inside our planet? One mysterious, mountainous blob lies under the Pacific Ocean. The other is under Africa and part of the Atlantic Ocean.

Even though scientists know the blobs slow down earthquake seismic waves, no one knows what their composition is. Researchers have argued back and forth for decades about whether the mountainous masses are made of dense piles of chemically unique rock; or rubbery lava plumes; or something else. Geophysicist Paula Koelemeijer at University College London says,  “We know less about what’s deep below our feet than we know about the surface of the Sun or the Moon or Mars.”

Without yet knowing what the actual composition and density of the huge moutain blobs are, it is difficult to understand their evolution. Were these hot mantle mountains responsible for the periodic supervolcanoes that have contributed to Earth extinction events?

University of Maryland Geologist and Professor Ved Lekis says Earth is the only planet known to contain plate tectonics, and recent research has suggested that tectonics may help sustain life by delivering a steady stream of nutrients, like nitrogen and phosphorus, to the surface. And yet researchers are not even sure what causes plate tectonic movement, let alone the gigantic mountainous blobs in the Earth’s mantle.

Prof. Lekis adds:  “I think that their real fundamental and philosophical appeal is their mystery. They are among the largest things inside the Earth, and yet we literally do not know what they are, where they came from, how long they’ve been around, or what they do.”
