The mantle makes up what percent of Earth's volume? What is the temperature of the Earth's mantle? How big is the mantle of the Earth? What percent of the Earth is the mantle? What layer of the Earth is part crust and part mantle?
The possible density inversion throughout seismic wave-guides beneath ocean basins and continental structures (without shields) is discussed in accordance with upper-mantle velocity models, thermodynamic properties of deep matter and temperature profiles. The problem is numerically solved. No density inversi...
Independent of the specific scenario for the Moon-forming giant impact, the Earth's mantle must have been largely or even totally molten (Nakajima and Stevenson, 2015; Lock et al., 2018). The solidification and fractionation in this last major MO set up the initial conditions for solid-state...
The formation of the earth's core was due to the density differentiation of the primitive matter of the earth. This differentiation should be in progress at the core-mantle interface in the present epoch. Redistribution of substances of various densities gives rise to large-scale convective ...
[1] We present a thermodynamic model of high-pressure mineralogy that allows the evaluation of phase stability and physical properties for the Earth's mantle. The thermodynamic model is built from previous assessments and experiments in the five-component CFMAS system (CaO-FeO-MgO-Al2O3-SiO2),...
It is shown that the obtained anomalous structures cause anomalies of the gravity field inside the Earth, which may be conducive to convective movements in the mantle and core.doi:10.3103/S0027134910020128N. A. ChuikovaT. G. MaksimovaAllerton Press, Inc.Moscow University Physics Bulletin...
