Ocean Sediments and Salts: What do they really tell us? Creation Perspective

Creation Answer:

“Every year water and wind erode about 20 billion tons of dirt and rock debris from the continents and deposit them on the seafloor,” so “the seafloor should be choked with sediment many miles deep.” On average, there is only about 1,300 feet of sediment, which is not even close to a mile deep. Sediment is known to be lost due to tectonic plate activity, but with everything taken into account, that 1,300 feet of sediment would take 12 million years to form and that’s it. However, that doesn’t cause a problem for us, because the global flood would have caused a lot of sediment to build up initially. Over about 3 billion years, there would be “250x more sediment than we see today.” This is a huge difference.

The argument that the sediments may not have accumulated that fast in the past still has other problems. The shape of the sediments off the coast is evidence of sediments being rushed off the continents quickly and not by a very slow process. The underwater landscape would look totally different if it had formed slowly over billions of years.

Ultimately, as erosion rates go, the continents would erode “into the ocean in about 14 million years.”[i] So how do we still even have continents, if the Earth has been changing for supposedly millions and billions of years?[ii]

Part of the sediments eroding into the water is salt, which is dissolved into sea water and thus giving the oceans a salty taste. So over time, as more erosion occurs, the oceans get saltier. “After 3 billion years, we would expect to see 70x more salt in the ocean than we see today.” 122 million tons of sodium are removed from the oceans each year, but this is not much compared to the 458 million tons that are added in that same time. Current salt levels would have only taken 42 million years to add up.

Again, to uphold an old earth point of view, one would have to claim that the rates of change were a lot different throughout history.[iii]

From an old earth point of view, these sediments and salts would be devastating to the evolution of ocean and land organisms. If the waters had too much sediment or salt, they would not be very suitable for life.

Evolutionists have to make large, extensive assumptions about the history of the Earth, whereas one assumption (accredited by God and history) that there was a massive worldwide flood over a short Earth history is a much simpler solution.

Any offensive language will automatically disqualify your comment for publication, even if the arguments contained are good. Please comment on the ideas that are presented and not the presenter.  If your comment becomes an ad hominem argument and does not substantially address the issue, your comment will be disqualified as well.  We are looking for real arguments, not fallacious ones, so that we can present and challenge opposing ideas and arguments as they are truly believed by evolutionists.  We do not want to tear down straw men as well as you do not want to be misrepresented. Also, please keep your comments as brief as possible, and if the majority of the comment does not address the current issue, but becomes a red-herring, it will not be posted as well. If your comment does not fall into one of the above restrictions, then your comment will be posted unedited (you may want to check your spelling, grammar, etc.) We thank you for your time and comments.

One thing to keep in mind, each blog is one piece of evidence. Evidence has to then be interpreted, which is not a fact…but evidence strengthening or weakening a specific hypothesis or theory. So there can be multiple ways of interpreting the same evidence. I am not being unscientific, but asking more questions and being skeptical is being more scientific. I am still working on these, so please help with your comments.
