Scientists have discovered two continent-sized regions, known as Large Low Seismic Velocity Provinces (LLSVPs), deep within Earth’s mantle beneath Africa and the Pacific Ocean. These structures are hotter, older, and more rigid than their surroundings, with larger mineral grains that resist mantle convection. Their edges are linked to volcanic activity, such as mantle plumes beneath … Read more
