Material from Earth’s Core Has Been Leaking into Mantle for Billions of Years | Geophysics, Geoscience | Sci-News.com

Earth’s magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source of this magnetic field is the core at the center of our planet. But the core is very difficult to study, partly because it starts at a depth of about 2,900 km (1,802 miles), making it too deep to sample and directly investigate
