Seafloor Spreading Matches Creation Predictions

Evolutionary scientists recently determined that seafloor spreading has been slowing down.1 And they are not exactly sure of the reason. However, this is no surprise to Flood geologists. It’s exactly what we predicted.2,3,4

Scientists from Brown University and University of California, Santa Barbara examined the spreading rates at 18 different ocean ridges.1 Studying the magnetic seafloor record, the team calculated the speeds of spreading for the last 19 million years, in evolutionary time.1 These ages correlate to the end of the Tejas megasequence, which we interpret to have occurred during the late receding phase of the Flood approximately 4500 years ago.2

According to conventional scientists,

The seafloor is destroyed in subduction zones, where oceanic crust slides under continents and sinks back into the mantle, and is reforged at seafloor spreading ridges…The crust's magnetic record tracks this pattern, producing identifiable strips every time the Earth's magnetic field reverses.5

Interestingly, evolutionary scientists found that the spreading rates first dropped 15-16 million years ago, in evolutionary time. Then they found that the rates dropped again by another 35% at 5-6 million years ago.6

In an unrelated and earlier study, conventional scientists found that the subduction rate at Borneo stopped at about the same time. They said, “As recently as 5 million years ago [Pliocene or Late Cenozoic], subduction stopped along the eastern margin of Sabah [Borneo] for reasons we do not fully understand.”7

Using satellite data, we can measure the rates the plates are still moving today. Most are moving only a few inches per year. However, many creation geologists think that the plates moved much more rapidly during the Flood year, at rates of several yards per second. Complex computer models by Dr. John Baumgardner showed that this type of movement is possible and likely to have occurred during the Flood year.3,4 These discoveries led to a completely new theory called catastrophic plate tectonics.8

Dr. Baumgardner also theorized that plate motion was controlled by the high-density contrast between the “heavier” original pre-Flood ocean lithosphere9 and the new “lighter” ocean lithosphere created during the Flood (formed at ocean ridges).4 He reasoned that the consumption of the older, denser material would have continued until the original oceanic plates were completely consumed by subduction. At that point, plate motion would cease abruptly because it no longer could subduct the newer, lighter crust.4

Is this why global seafloor spreading has slowed dramatically? And is this why subduction ceased at Borneo at about the same time? It seems most likely.

Also, the timing for the most intense rate change is exactly as predicted by Flood geologists. The greatest slowing of spreading rates and subduction rates coincide with the Early Pliocene (latest Tejas megasequence) when most of the world’s plates had also nearly stopped. This is also when we see that the Flood had nearly drained off the continents completely, creating the high Cenozoic Flood boundary.2

Sadly, most evolutionary geologists reject the idea of rapid plate motion in the past. They refuse to consider runaway subduction because it suggests a global catastrophe like that described in Genesis. It is unfortunate that the secular world has been so willingly blinded to the truth of the global Flood. It explains so much of what we observe.

Fossil Insect Predation Shows No Evidence of Evolution

Fossil Insect Predation Shows No Evidence of EvolutionSome recent science news stories have come out describing fossils of insects feeding on plants supposedly many “millions of years ago.” What is amazing is the fossil plants and insects are just like the ones we find alive today.1 All that is different are the grossly inflated evolutionary ages (‘deep evolutionary time’) unnecessarily forced on them.More...

Adaptive Genetic and Epigenetic Changes in Plants

Adaptive Genetic and Epigenetic Changes in PlantsBeing sedentary organisms, plants are essentially stuck where they are planted and need to dynamically adapt to the conditions around them to not only survive but thrive. They do this by constantly detecting changes in their environment with a huge host of sensors in their leaves, stems, and roots.More...
