Earth is unique in our solar system for having an enormous quantity of surface water. Given that the inner core is constantly expanding, and thus the surface area of the Earth is also expanding, and considering that ocean water levels are continuing to rise (as demonstrated by the continental shelf, which was once above the surface and is now 600’ below), where does all the water come from?
There is another attribute our world has that is not found on the other worlds of our system—we are covered with life, and an enormous variety of forms. Water and Life must be related.
As it turns out, most land-based ecosystems produce more water than they consume. Plant bacteria in particular, excrete water as a “waste product” by consuming oxygen and hydrocarbons. It is reasonable to assume that our hydrosphere is a by-product of the life of the land. As the amount of life increases, so does the depth of the water. It is a good thing that the Earth is expanding, or we would be a water world by now.
Considering that water is generated by life, rather than a geological process, we can now proceed to refine our view of the crust of the Earth.
Examining the crust, we find that under its original formation, the top layers of the molten asthenosphere solidify, as the lighter elements move to the surface. Over this solid crust of gabbro basalt, meteoric dust and rock fall, forming a second, lighter crust mainly of silica and aluminum (stony meteorites). This is a typical crustal formation of a planet like Venus, where no hydrosphere exists. Geophysicists name these two crustal layers Simatic and Sialic, after the primary elements of their composition—Silicon / Magnesium (gabbro basalt, SIMA for short), and Silicon / Aluminum (or SIAL for short).
The Earth expands; the outer crust (both layers) crack open, and through the cracks pour magma, which solidifies to more SIMA. We now have a surface where the SIMA is exposed, and at a lower elevation than the surrounding SIAL sitting on top of the SIMA. These great basins become the repositories for the water generated by the microscopic life forms existing in the SIAL layer, and develop into seas and oceans. The SIMA thus forms an underlying, global crust with large cracks, making tectonic plates. The SIAL forms the continents.
The interesting conclusion—life did not form in the oceans, life started out on the land, and formed the oceans, in which higher forms of life evolved, which moved back on to the land. Since the amount of water is constantly increasing on the planet, as the continental shelves were at one time exposed to the air, it is an indication that the time may be near for another quantum expansion of the planet.
