Mankind has been solicitous about the ascent of oceanic surface since middle period of 20 century, while it become warmer globally, and it became a fashionable topic in media movies and popular article.
However, some Chinese propose a new idea named hydrosphere-spending hypothesis recently: Water in the hydrosphere of the earth is always spent in the evolutional process of the earth. For long time scope, instead of the ascent of the oceanic surface, the difficulty for mankind and whole biosphere is the decent of oceanic surface.
According to hydrosphere-spending hypothesis, the process of losing water in the hydrosphere contains three main links:
A, the methane and oxygen are produced in the biosphere while the water is spent;
Bthe oxygen is absorbed with interior substance of the earth in the process sea-floor spreading with the convection of earth mantle;
C the methane is decomposed to hydrogen by ultraviolet radiation of the sun, and then the hydrogen escaped to outer space with the factors thermal movement of hydrogen atom, earth rotation and pressure of the sun-light.
According to hydrosphere-spending hypothesis, forepart of the earth was surrounded by water completely, no land basset out the surface of the ocean, though the lithospheres of continental type and oceanic type had existed.
According to hydrosphere-spending hypothesis, Cambrian explosion was the period of corresponding to first land appears in the ocean. Biosphere became flourishing, and hydrosphere spending is also accelerated accordingly. It is estimated, the hydrosphere has lost two times water of that in the ocean nowadays.
You are welcomed to oppugn and renew hydrosphere-spending hypothesis.
