Earth’s Hidden 'Fortresses' Are Massive!

Scientists just found gigantic 'fortresses' lurking 1,800 miles beneath our feet—think continent-sized blobs of hot, ancient rock under Africa and the Pacific. These monsters, called LLSVPs, are older and tougher than anything around them and might be behind volcanic hotspots like Hawaii and even past mass extinctions! Basically, the stuff deep inside Earth is way wilder than we thought, and it could be shaping the surface in ways we’re only starting to understand. #Science #EarthScience #Geology
