Review—Implications—Conclusion
As the reader reaches the close of this presentation he is therefore urged to keep foremost in mind the two illuminating, all-important, basic conceptions of the theory, to wit; first, that terrific, implacable heat—far, far more intense than mere solar heat received by Earth—was absolutely necessary to set the stage for a glacial age; and second, that the frozen moisture which built ice sheets in some areas and the liquid water which made pluvial conditions elsewhere were not evaporated surface water, but primitive, virgin water—water which was falling to Earth’s surface for the first time; water which was responsible for increases in Earth’s hydrosphere—increases which so very evidently have occurred from time to time since the first descending increments, far, far back in pregeological eras, were permitted to remain upon the slowly cooling crust.
