Very little sediment on the ocean floor would confirm a young earth

If sediments have been accumulating on the seafloor for three billion years, the seafloor should be choked with sediments many miles deep.



Every year water and wind erode about 20 billion tons of dirt and rock debris from the continents and deposit them on the seafloor. Most of this material accumulates as loose sediments near the continents. Yet the average thickness of all these sediments globally over the whole seafloor is not even 1,300 feet (400 m).

Some sediments appear to be removed as tectonic plates slide slowly (an inch or two per year) beneath continents. An estimated 1 billion tons of sediments are removed this way each year. The net gain is thus 19 billion tons per year. At this rate, 1,300 feet of sediment would accumulate in less than 12 million years, not billions of years.

This evidence makes sense within the context of the Genesis Flood cataclysm, not the idea of slow and gradual geologic evolution. In the latter stages of the year-long global Flood, water swiftly drained off the emerging land, dumping its sediment-chocked loads offshore. Thus most seafloor sediments accumulated rapidly about 4,300 years ago.


Figure 1: Every year, 20 billion tons of dirt and rock debris wash into the ocean and accumulate on the seafloor. Only 1 billion tons (5%) are removed by tectonic plates. At this rate, the current thickness of seafloor sediment would accumulate in less than 12 million years. Such sediments are easily explained by water draining off the continents towards the end of the Flood.
