If this flood was literal and global, then we are confronted with the "Mount Everest" problem. Located in Nepal, Mount Everest is the Earth's highest peak. It is also the highest peak in a range of mountains stretching across 1,500 miles and containing more than 1000 peaks higher than 20,000 feet.
Mount Everest is presently at a height of 29,028 feet above sea level and getting taller at the rate of about 3-5 millimeters per year. Assuming the tectonic uplift rate of the Himalayan range has been uniform since the days of Noah's flood, Mount Everest would have been only about forty-three (43) feet shorter (28,985 ft.) back in Noah's day. That is still a considerable height, equal to about 5.5 miles above present sea level.
It would take a lot of water for the flood to reach that depth - more water than is presently above the crust of the earth. Where did so much water come from and where did it go after the flood?
Before answering that question, let's put this puzzle into perspective. Our Earth is about 25,000 miles in circumference. If it was compared to the size of a basketball, the Earth's crust would be about as thick as a sheet of tissue paper wrapped around it. In a global perspective, 5.5 miles of water above today's sea level is a relatively minute quantity, increasing overall circumference by only 0.044%. Of course, to people on the order of five to six feet in stature, 5.5 miles is a lot. The thing to keep in mind is perspective.
Many Young Earth Creationists espouse the theory that most of the Earth's mountains and sedimentary rock strata were formed underwater during Noah's flood by massive global volcanic and tectonic activity. They then conclude that because the mountains formed during the flood, not as much water was needed to cover the Earth to "fifteen cubits" above the highest mountain as Genesis 7:20 requires. Nice try, but no prize.
That answer does not meet the Scriptural or geophysical requirements, as the Bible clearly says that the mountains were already there, and by implication, the continents and tectonic plates were in their present-day locations, give or take a hundred yards to account for 4,000+ years of continental drift. Additionally, the alleged underwater volcanic and tectonic activity, on such a massive scale as proposed by Young Earth Creation Science models, would have produced a great deal of acid which would be detectable as SO4 ions in the Greenland Ice Sheet core record. That evidence is simply not there. This is covered in more detail in a later chapter.
Instead of taking the usual approach - that Noah's Flood could not have happened because of this fact or that fact - let's approach the problem from this angle: Noah's Flood did happen because the Bible is true, so let's try and find answers that can fit the facts, both scientific and Biblical. After all, Jesus Himself confirmed that the flood was a real event (see: Mt 24:37-38; Lu 3:36; Lu 17:26-27), so there must be an explanation.
Notice that the Lord says the agency of destruction would be the Earth itself. The planet Earth has three spheres: the core, mantle, crust (lithosphere), the seas (hydrosphere), and the air in the heaven above (atmosphere).
According to the Scriptures, there were two (2) related sources for the rains and waters of Noah's flood. There were "fountains" of water coming up out of the Earth and there was water coming down from the "windows" of heaven. We will deal with the matter of the fountains first, as they began first and triggered a complex chain reaction from below the Earth's crust that then affected things far into the upper atmosphere.
Two types of water fountains occur in nature.
One is called an Artesian well/spring.
Artesian wells occur when a hole penetrates into the earth to a region where internal pressure causes the water to flow upward like a fountain.
The internal pressure that drives such fountains is produced when the head of the particular water table penetrated is at a higher elevation than the spring opening. The principle is similar to the gravity pressure that drives water out of your sink tap because the city water supply is stored in an elevated tower above the town.
The second type of fountain is called a geyser.
Geysers occur when waters in underground chambers are heated by the surrounding host rock until the pressure and temperature cause them to flash to steam and erupt upwards. When the chamber is emptied, replacement water flows back into the chamber, the replacement water is heated, and the cycle repeats. An excellent example of this is seen in Yellowstone National Park's "Old Faithful" geyser.
According to what is written in the Scriptures, the fountains of Noah's flood may have been a similar form of geyser activity on a massive, world-wide scale, concentrated along the mid-oceanic ridge system. A careful reading of Genesis 7:6-10 indicates that the flood waters were already rising for about seven days before the fountains "were broken up" (note verse: 11).
Careful parsing of the above passage indicates that great amounts of water were already being added to the Earth's seas at least seven days before the rains even began. This means that sea level was already rapidly rising, flooding low lying coastal areas and sending panicked low-land inhabitants inland from the rising seas. Meanwhile, presumably up on much higher ground, Noah and his family took shelter on the Ark and waited, while the massive gopher wood vessel remained firmly nested in its construction frame, unmovable and secure until the rising waters lifted it from its resting place.
The great volume of water this early in the flood event could only come from massive undersea "fountains" beginning to breach the crust all along the mid-oceanic ridge system. But this preliminary out-flow was still insufficient to breech the ocean's surface. The volume of underwater displacement would, however, be sufficient enough to generate global tsunami (tidal waves) activity, quickly drowning inhabitants who lived near the seas.
Seven days into the flood the undersea fountains broke through the crust in full fury, and the pressure of the flow sent scalding columns of superheated waters upwards, breaching the ocean's surface and erupting skyward as a globe-encircling curtain of steam rocketing into the upper atmosphere. As the steam came into contact with the colder air it would condense and produce cloud cover and relentless rainfall on a planetary scale.
The second passage says the rains ceased only AFTER the fountains stopped. This is fully consistent with a geyser model.
As briefly mentioned earlier, the most likely geological location for the "fountains" (geysers) was along a narrow, globe encircling series of underwater Tectonic Plate boundaries called the mid-oceanic ridge, where the Earth's oceanic crust is currently spreading apart at the rate of a few centimeters per year. This continuous system of faults is seen on a map of the Earth's sea floors as running south down the middle of the Greenland Sea and the North and South Atlantic Oceans. It then extends eastward into the Indian Ocean basin, onward between Australia and Antarctica and into the great Pacific Ocean basin. It then continues northward along the eastern side of the Pacific basin.
Scientists are studying what they term as a large "open wound" where the Earth's oceanic crust is missing deep under the Atlantic Ocean near that ridge system. What scientists are keen to know is whether the crust was ripped away by huge geological faults, or whether it never even developed in the first place.
Could this be an actual location where the fountains of the great deep were "broken up" as the Bible indicates? Read the story: Serpentinite not crust, scientists to find out how part of Earth's crust went missing.1)Serpentinite not crust, scientists to find out how part of Earth's crust went missing.
The geysers' source would have been extensive underground reservoirs of magma supersaturated with water that had collected in the regions below the boundary of the oceanic crust and above the underlying mantle region. The next graphic is a simplified schematic cross-section of the Atlantic Ocean basin, with the mid-oceanic ridge at the center.
Here is an important question to note:
Why would magma, supersaturated with water, only accumulate under the crust of the oceans and not under the continents?
There are two reasons.
First, water, being much lighter than rock, would have gravitated upwards until it was blocked by the crust. It would then tend to pool between the Crust-Mantle boundaries.
Secondly, because the Earth's crust is much thinner under the ocean floors (5 - 12 km) than under the continents (35 km average), it would naturally pool where the Earth's crust was thinnest - under the basaltic oceanic basins which ride higher on the mantle.
The underground region where this water-saturated magma would have collected is above a zone called the Asthenosphere,2)Asthenosphere commonly known as the Mohorovic discontinuity.
The behavior of seismic waves passing through that region appears to show relative liquidity as compared to the rock in the regions above and below it.

Scientists are just now finding evidence to confirm the presence of large volumes of water deep inside the Earth, enough to fill Earth's ocean basins 10 times over (see also Earth Mantle 'Ocean': 3-D Seismic Model Of Vast Water Reservoir Revealed).5)Earth Mantle 'Ocean': 3-D Seismic Model Of Vast Water Reservoir Revealed
Only a fraction of such an amount would be required to raise sea levels to meet the requirements of Noah's flood. By the way, long before scientists learned there were vast amounts of water under the Earth, the Bible already hinted at this fact (see Exodus 20:4.)
If a large volume of water-saturated magma had pooled under the Earth's ocean basins, it is probable that the oceans were much shallower back then as compared to the Post-Flood times of today. Earth's sedimentary geology is replete with evidence of shallow-water depositions. And that same geology reveals fluctuations in global sea levels across geologic time that greatly exceed what could possibly be caused by accumulations and melting at the polar caps. One of the possible explanations put forth to explain this mystery is "sea floor warping" and periodic accumulations and releases of waters from supersaturated magma, as proposed in this model, and that could account for this observation. In addition, it would be more likely that a rupture in the crust would occur, and these waters released, if the accumulation of magma below the oceanic crust was placing great upward pressure against the crust.
Therefore, we will assume that at the time just before Noah's flood the seas were more shallow than today. If this was indeed the case, then explaining how much of the flood waters rapidly receded becomes simple to explain.
Basic law of Physics:
For every action there is an equal and opposite reaction.
After the great volume of waters which were formerly trapped below the Earth's oceanic crust jetted upwards, condensed, and fell into the regions above the oceanic crust, they quickly began to produce an accumulative great reverse-pressure on the thin crust of the ocean floor.
In the meantime, because of the sudden release of the great pressure in the supersaturated magma below the crust, there would have been a relative cooling effect on the remaining magma body.
This cooling, along with the loss of the volatiles (the waters), would reduce the volume of the underlying magma chamber, causing it to shrink. This would facilitate the crust being pushed downward by the weight of the surface waters above and thus forming the vast Abyssal plains on both sides of the mid-ocean spreading ridge.
Based on sea mount and Continental Shelf evidence (discussed in detail in the chapter concerning the Days of Peleg),6)CREATION 16: sea level after Noah's flood abated to a level about 1,000 meters higher today than it was before the flood.
And that is the basic proposed geologic component of the Flood Model.
In the next chapter you will learn about the complex chain reaction this triggered in the Earth's atmosphere and the resultant changes that sharply decreased the life-span of man on this side of the flood.
Before proceeding to other aspects of the flood event, we need to address an objection to this geologic model posed by accepted plate tectonic theory: If seafloor spreading and volcanic activity along the mid-oceanic ridge has been ongoing for millions of years, what explains this anomalous eruption of waters at this particular point in the Earth's history? This is a fair question, for which I only have a Biblical answer.
This "mist" seems to indicate that there was a great deal of heated water present under the Earth and relatively close to the surface, or at least making its way to the surface at various places in order to produce this mist. A Divine reconfiguration of the Earth's geology, during the process of the seven days of Genesis when God made the "foundation of the world" (See the chapter entitled "Creation or Catabolism?"), is the only possible explanation. Surely the Lord knew that He had created an unstable situation that would eventually cause the flood centuries later in the days of Noah. Granted, this is not a scientific answer, but one that is theologically sound given our understanding of God's omnipotence and foreknowledge.
The bottom line is that the geologic conditions that produced the massive geysers of Noah's days, however they came about, no longer exist. Therefore, there can be no repeat of this activity on such a great scale (See Genesis 9:15 for confirmation). In other words, the very mechanics and conditions that produced the great flood event self-destructed upon completion of the flood event cycle, thus the geologic changes became permanent. So, unlike the "Old Faithful" geyser, this was a one-time event.
In the next chapter we will discuss why the age-span of mankind greatly decreased after the flood. We will also explain how Noah and his family, to say nothing of all sea creatures, survived being par-boiled by the heat released when the massive geysers erupted in the middle of the Earth's great oceans.
