The composition of the Earth’ core is poorly constrained beyond its major constituents (i.e. an Fe-Ni alloy). s Density contrasts between the inner and outer core boundary are used to suggest the presence ( - 10 + 5%) of a light element or a combination of elements (e.g., 0, S,...
This chapter describes the composition of the earth. The geophysical, geochemical, and geological characteristics of the Earth reveal much about the planet's overall system. However, when describing the whole body, such information requires considerable integration and interpretation to see through the ...

As the primordial Earth heats up and produces differentiation, gas released from the earths interior forms the atmosphere. The early component of the earth atmosphere and modern, it is because of the reaction between UV radiation energy causes the original composition of the atmosphere, generating ...
The Chemical Composition of the Interior Shells of the Earth The suggestion is made that the core and lower mantle of the Earth are chemically analogous to the two principal components of highly reduced enstatite cho... JM Herndon - 《Proceedings of the Royal Society A Mathematical Physical & ...
