Unveiling Earth's Ancient Ocean Floor: A Mysterious Core Revelation

Scientists have created a detailed map of the geology beneath Earth's southern hemisphere and believe that an ancient ocean floor may be encasing the planet's mysterious core. This discovery could explain why the core is hotter than the mantle above it. The "recycled" ocean floor acts like a blanket, trapping heat inside the core. The findings provide insights into the Earth's formation and could help understand plate tectonics and the planet's evolution over time.
