When earth's mantle meets its core: Findings boost hypothesis of deep magma ocean

Earth's mantle and its core mix at 2900 kilometers under our feet in a mysterious zone. A team of geophysicists has just verified that the partial fusion of the mantle is possible in this area when the temperature reaches 4200 Kelvin. This reinforces the hypothesis of the presence of a deep magma ocean. The results have an effect in the understanding of the dynamics, composition and formation of the depths of our planet.
