In addition, he determines that about 10% of the ark was needed for food (compacted to take as little space as possible) and 9.4% for water (assuming no evaporation or wastage). (Imagine if you had to stay in an area the size of a closet for a year.) How were several thousand diverse kinds of animals exercised regularly? How did a crew of eight manage a menagerie larger and more diverse than that found in zoos requiring many times that many employees? The water would be steam by the time it reached the surface of the earth. John Baumgardner created the runaway subduction model, which proposes that the pre-Flood lithosphere (ocean floor), being denser than the underlying mantle, began sinking. 119-144 In: Poldervaart, A., ed., Crust of the Earth, Geological Society of America Special Paper 62, Waverly Press, MD. Tree ring records go back more than 10,000 years, with no evidence of a catastrophe during that time. These layers can occur more or less at random times in the geological history, and have characteristic fossils on either side.
At least 25% of the space would have been needed for corridors and bracing. Woodmorappe claims that eight people could care for 16000 animals, but he makes many unrealistic and invalid assumptions. The heat released in the process decreased the viscosity of the mantle, so the process accelerated catastrophically. Patterns of ocean circulation over the continents during Noah's Flood. Patterns and processes of vertebrate evolution, Cambridge University Press. Miracles in, creationism out: "The geophysics of God". [Becker & Kromer, 1993; Becker et al, 1991; Stuiver et al, 1986] Alley, R. Therefore, if the fossils were themselves laid down during a catastrophic flood, there are, it seems, only two choices: (1) the salt layers were themselves laid down at the same time, during the heavy rains that began the flooding, or (2) the salt is a later intrusion.
Additional clean animal figures assume they are taken aboard by sevens, not seven pairs, and also assume juvenile animals. (Brown proposes that the cataclysms were caused by the crust sliding around on a cushion of water; Whitcomb & Morris don't give a cause.) Austin, Steven A., John R. How does a flood explain the accuracy of "coral clocks"? Geological Highway Map of Nova Scotia, 2nd edition.
"Total mass after one year" is the maximum load which Woodmorappe allows for. The earth's terrain, according to this model, was much, much flatter during the Flood, and through cataclysms, the mountains were pushed up and the ocean basins lowered. How are these observations explained by a sorted deposition of remains in a single episode of global flooding?
(The summit of Everest is composed of deep-marine limestone, with fossils of ocean-bottom dwelling crinoids [Gansser, 1964].) If these were formed during the Flood, how did they reach their present height, and when were the valleys between them eroded away?
They thus seem to require at least two periods of deposition (more, where there is more than one unconformity) with long periods of time in between to account for the deformation, erosion, and weathering observed. Many very tall mountains are composed of sedimentary rocks.
He then calculates that this would increase the total animal mass by 2-3% and decides that this amount is small enough that he can ignore it completely. It is important to take the size of animals into account when considering how much space they would occupy because the greatest number of species occurs in the smallest animals. Vermicomposting could reduce the rate of waste accumulation, but it requires maintenance of its own. The biology of spiders, 2nd ed., Oxford University Press, New York. The following objections are covered in more detail by Brown. Walt Brown's model proposes that the Flood waters came from a layer of water about ten miles underground, which was released by a catastrophic rupture of the earth's crust, shot above the atmosphere, and fell as rain. Kent Hovind proposed that the Flood water came from a comet which broke up and fell on the earth. [Johnsen et al, 1992,; Alley et al, 1993] A worldwide flood would be expected to leave a layer of sediments, noticeable changes in salinity and oxygen isotope ratios, fractures from buoyancy and thermal stresses, a hiatus in trapped air bubbles, and probably other evidence. Why did the Flood not leave traces on the sea floors? [Twenhofel, 1961] In a year of the Flood, they could have settled about half a meter. Such layers are sometimes meters in width, interbedded with sediments containing marine fossils.
However, even Jewish sources admit that this contradicts the unambiguous word of the Bible. 187] The number and size of clean birds is small enough to disregard entirely, but the Bible at one point (Gen. Woodmorappe performed such an analysis and came to the conclusion that the animals would take up 47% of the ark. How did such a small crew dispose of so much waste? The animals aboard the ark would have been in very poor shape unless they got regular exercise. Again, this has the problem of the heat from the gravitational potential energy. A year long flood should be recognizable in sea bottom cores by (1) an uncharacteristic amount of terrestrial detritus, (2) different grain size distributions in the sediment, (3) a shift in oxygen isotope ratios (rain has a different isotopic composition from seawater), (4) a massive extinction, and (n) other characters. Why is there no evidence of a flood in tree ring dating? This apparently occurs when a body of salt water has its fresh-water intake cut off, and then evaporates.
