How the Earth's Plate Tectonic Cycle Works by John Carman

By John Carman

"The early life of the sea flooring (0- .3Ma) verses the age of plate tectonics (2-3 Ma) indicates strongly that plate tectonics is cyclic. Densified silicate liquid(Ls) at approximately 290km intensity means that it can be the factor that lightens the outer center in addition to an lively factor in its actions in addition to reduce mantle levels excessive density magnesium provoskite (MgPv), calcium perovskite (CaPv), magnesiumwustite (Mw), iron(Ir) and iron liquid(Lm) plus isobarically and isothermally invariant liquid levels. volatile convective contacts between those levels in any respect degrees produce warmth as they generally tend towards reliable equilibrium. This warmth expands opposed to the earth's mantle or even motives the internal center to soften with 5ccg. finally, the core-mantle boundary fails alongside strains and / or issues to permit for the go out of densified silicate liquid. This liquid reacts with the decrease mantle to provide specified beverages FOZO for oceanic island basalts and C-Component for the ridge and upward thrust basalts ofthe Atlantic, Indian and Pacific oceans. it truly is suggestion that those ejected beverages react to shape scorching sturdy plumes of low viscosity that ascend to 290 km the place they soften on decompression to basalt that ascends additional to create oceanic crust. Sea-floor spreading through subduction to the earth's center the place the cycle ends to begin... repeatedly. A hypothetical ternary approach is used to demonstrate the cycle from commencing to finish. Experimental facts exhibits that the core-mantle boundary can be so simple as a quaternary reaction:

MgPv + CaPv +Mw = Ls + Lm, the place Ls most likely includes a few Fe203.
