a wind
Genesis 8:1
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.
