4. Thus the fountains of the great deep and the windows of heaven (Genesis 7:11 and 8:2) are interpreted in this CPT model in terms of the above-postulated linear geysers; water displaced onto the continents by the freshly raised ocean floors is also suggested as a possible water source. Austin et al. (1994) also suggest, referring to Genesis 7:24–8:2, that the latter would have remained a source of water for up to 150 days;
5. Rapid plate motion would have ceased when virtually all the pre-Flood oceanic floor had been replaced with new, less-dense, less-subductible rock. The lack of new, hot mantle material would have stopped the spreading-center geysers and resulting global rain. Austin et al. (1994) refer this point in time to Genesis 8:2;
6. Warm oceans immediately after the Flood follow naturally from this CPT scenario, and form an essential part of Oard’s (1990) model of an Ice Age in a young-earth framework. Present-day isostatic crustal movements, earthquakes and volcanoes also follow naturally as representing “relict Flood dynamics.”
