Unveiling Earth's Enigmatic Subterranean Giants: Core's Towering Underground 'Mountains'

Scientists have discovered an ancient layer between the Earth's core and mantle, known as the Core Mantle Boundary, which could contain underground mountains up to five times taller than Mount Everest. This layer, composed of dense, subducted ocean floor, slows seismic waves and could play a significant role in heat escape from the Earth's core and the generation of magnetic fields and volcanic eruptions. Further research is needed to determine the extent of this layer and its impact on Earth's processes.
