interval of time, the amount of matter-energy of a planet being transformed into the Sun’s core is always greater than that of the solar-sourced matter-energy, therefore, in the sun-planet-scaled coevolutionary process, the planet is actually a mass-loser while the sun is the mass-gainer...
is called the core. It is about 2,200 miles thick. The core is extremely hot - about 7,200 degrees F. The core is further divided into an inner core and an outer core. The outer core is a liquid layer of melted nickel and iron. The inner core is made of solid nickel and iron....

takes place on the hundreds of femtosecond time scale and corresponds to water molecules in the outer layer bulk-like region of the molecule. This is followed by the collective water/side-chain orientational dynamics that take place on the few picosecond timescale. And lastly, the cooperative wat...
Noble gas isotopes in plumes require a source of primitive volatiles largely isolated in the Earth for 4.5 Gyrs. Among the proposed reservoirs, the core is gaining interest in the absence of robust geochemical and geophysical evidence for a mantle source
