Earth dons a different mantle

The Mantle of the Earth

In the first decade of this century physicists discovered that the atom had a massive central core which they called a nucleus, and geophysicists discovered that the earth had a massive central nucleus which they called a core. The study of the interior of the atom, the smallest building block of matter, and the study of the interior of the earth, the largest piece of matter to which man has di...

The earth dynamic system: the earth rotation vs mantle convection

The earth dynamic system is one of the key scientific questions on the earth science. The thermodynamic behavior and gravity force of the earth and the rheology nature of the mantle prove that mantle convection is the main power source leading the lithosphere to break and move. Yet the directivity of both the structures in the crust and plate movement reminds of the earth rotation. Here we demo...

Mantle and Core of the Earth

Dynamic Earth: crustal and mantle heterogeneity*

The dynamic processes within the Earth leave their record in geophysical and geochemical variation about the general stratification with depth. A snapshot of current structure is provided by geophysical evidence, whereas geochemical information provides a perspective over the age of the Earth. The combination of information on the distribution of heterogeneity from geophysical and geochemical s...

Geo-neutrinos, Mantle Circulation and Silicate Earth

In preparation to the experimental results which will be available in the future, we consider geo-neutrino production in greater detail than in [F. Mantovani et al., arXiv:hep-ph/0309013], putting the basis for a more refined model. We study geo-neutrino production for different models of matter circulation and composition in the mantle. By using global mass balance for the Bulk Silicate Earth,...
