Recently, scientists have made a shocking discovery that could change our understanding of the Earth. They’ve discovered huge blobs of material deep in the Earth’s mantle, about 660 miles below the surface, that are completely different from the surrounding rocks. This material, which has been named “ultra-low velocity zones,” could be up to 10 times more viscous than the surrounding rocks and may even contain unknown elements. This discovery could shed light on the Earth’s formation and evolution, as well as potentially provide new insights into the planet’s composition and behavior.
