Geologists just uncovered massive 'fortresses'—think continent-sized blobs—almost 1,800 miles beneath our feet in the Earth’s mantle! These ancient, super-hot zones (called LLSVPs) are way tougher than the surrounding rock and might be steering everything from volcanic eruptions to the drift of continents. Turns out, Earth’s insides are way less mixed up than we thought, and these hidden giants could be the real power players shaping our planet’s surface. #Science #EarthScience #Geology
