Subterranean 'supercontinents' reveal intriguing new clues to what's happening beneath Earth's surface

The article from CNN discusses a groundbreaking study published in the journal *Nature* that suggests the Earth's mantle contains remnants of ancient supercontinents. Researchers from the University of Sydney used advanced seismic imaging techniques to map out structures deep within the Earth, revealing what they believe to be the remains of continents that existed billions of years ago. These findings indicate that the mantle, traditionally thought of as a uniform layer, might actually hold clues to Earth's geological history, including the formation and breakup of supercontinents like Nuna, Rodinia, and Pangaea. The study proposes that these ancient landmasses could have left behind "roots" or "scars" in the mantle, which have influenced the planet's tectonic activity over time. This discovery not only reshapes our understanding of Earth's internal structure but also provides insights into the long-term geological processes that have shaped our planet.
