Subterranean Flood-Sick Blues

Genesis 7:11 provides and interesting detail concerning the Great Flood. "...on that day all the fountains of the great deep were broken up, and the windows of heaven were opened."

So as the Scriptures tell, there was water coming down in the form of rain for forty days; and water was also being released in vast quantities from great, broken-up, subterranean fountains. 

It is the view of Flood geologists that prior to the Flood, the tectonic plates were one whole, unbroken layer of the earth. In this view, the tectonic plates are the broken-up "fountains of the deep". 

Certainly, the Flood of Noah's time changed the face of the earth. Prior to that Flood, the earth was not as topographically extreme as it is in our time. There were hills and mountains from the time of creation. But there was nothing like the highest mountains or the lowest valleys and basins of our time. 

Most of the mountains on the earth at present are composed of sedimentary layers, which were laid down by the Flood, and have become bent and pushed up by shifting tectonic plates.

This explains why there are fossilized clam shells at the highest points of the earth. It also explains why bent layers of sedimentary rock are not fractured and broken. They were still soft when they were pushed up and bent by tectonic activity.

The topographical extremes of the post-Flood world ensure what God Himself decreed, that He will never flood the whole earth again, as He did in those days (Genesis 9:11-17).

But the final judgment of sin will come by fire. As the Scriptures tell: 

"But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up. Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness, looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat? Nevertheless we, according to His promise, look for new heavens and a new earth in which righteousness dwells" (2 Peter 3:10-13).
