Scientists have uncovered a massive, hidden rock layer beneath Bermuda, over 12 miles thick, defying typical oceanic island formation. This unusual geological structure, less dense than the surrounding mantle, may explain why Bermuda sits unusually high above the Atlantic. The discovery, made using seismic waves, suggests a link to Earth's ancient past and the breakup of the supercontinent Pangaea.Scientists have uncovered a massive, hidden rock layer beneath Bermuda, over 12 miles thick, defying typical oceanic island formation.
