New Defender's Study Bible Notes
8:1 a wind. The uniform temperatures of the pre-Flood would have prevented the great atmospheric circulations that now prevail, so that significant wind movements were impossible. With the almost complete precipitation of the waters in the primeval canopy after 150 days, the present latitudinal temperature differentials were soon functioning to initiate tremendous winds all over the earth. These winds, blowing on a shoreless ocean, would certainly generate gigantic surface waves and tidal surges. The latter, superimposed on all the other hydrodynamic and geophysical forces at work, evidently served as the critical factor to trigger great tectonic forces that eventually would restore at least partial equilibrium to the disturbed surface of the earth. The earth’s crust was in a highly unstable condition, with the tremendous subterranean reservoirs now emptied of their pressurized waters and with vast depths of light sediments piling up in the antediluvian sea basins.
8:1 assuaged. As a result of the water subsiding, the phenomena described in Psalm 104:6-9 began to take place. The earth’s crust collapsed deep into the previous subterranean reservoir chambers, forming the present ocean basins, and causing further extrusions of magmas around their peripheries and through openings in their floors. The light sediments in the sea troughs were forced upward by isostatic readjustment to form mountain ranges and plateaus. Thus the waters originally stored in the vapor canopy and the subterranean chambers are now stored mainly in the present ocean basins (these waters would be sufficient to cover a “smoothed” earth to a depth of almost two miles) after the vast topographic adjustments that terminated and followed the Flood.
