Despite decades of research, scientists remain divided about many of the processes taking place beneath our planet's surface, including details about the churning of molten metals in the Earth's core which creates the magnetic field that protects the planet from deadly solar radiation. Two massive formations of incredibly hot molten rock the size of continents are lurking underneath Earth's surface, one of them situated under Africa and the other below the Pacific Ocean. Now, for the first time, Quanta Magazine has created a neat 3D model of the formations, situated in the area where the Earth's molten iron core meets its rocky lower mantle, showing the formations as they appear to leak outwards and upwards toward the crust. The model provides an important visual cue which challenges the commonly held view of Earth that one might find in a science textbook, which shows geometrically clean, spherical orbs of mater starting with the solid inner core, the outer liquid core, the lower and
