The planet’s core has revealed a huge slab of folded Earth! It can once be a part of the ocean floor, scientists contemplate. With this discovery, a theory on the Earth’s crust got strengthened. It is been said that the earth’s crust is constantly recycled. And this happens, as molten material from below the crust simultaneously pushes up to refresh the surface.
The still-to-be-proved structure is about 125 miles deep, with its width of at least 125 miles in the north-south direction. Alex Hutko, a graduate student of the University of California, Santa Cruz said,
If you imagine cold honey pouring onto a plate, you would see ripples and folds as it piles up and spreads out, and that’s what we think we are seeing at the base of the mantle.
He is also the lead author of a paper that describes the discovery in the May 18 issue of the journal Nature.
