The word “prevailed” in the original conveys the meaning “were overwhelmingly mighty.” Not only would all land animals eventually drown, but the plant covering would be uprooted and rafted away, the soils eroded and finally even the mountains and hills washed away. In the sea depths, the eruption of the fountains of the great deep would also profoundly affect marine life. Great quantities of magma, metals and other materials were extruded from the earth’s mantle. The sediments from the lands were transported down to be deposited in the encroaching sea basins. Complex hydrodynamic phenomena–tsunamis, vortices, turbidity flows, cyclic erosion and deposition, and a variety of geomorphologic activity–took place throughout the year. Earth movements of great magnitude, and tremendous volcanic explosions shook the earth again and again, until finally, “the world that then was, being overflowed with water, perished” (II Peter 3:6).
