Depositional Features of a Worldwide Flood

Lack of Soil Layers and Bioturbation

The same reasoning can be applied to other land features. If sediment layers were deposited with periodic exposure to dry land over many millions of years, as maintained by uniformity theory, sediment layers found worldwide would show evidence of soil accumulation and physical disturbance by plant and animal life (commonly referred to as bioturbation) similar to today’s environment.

Life is impossible without a soil layer and we know from the fossil record that abundant populations of animals, plants, and burrowing animals existed throughout much of earth’s history. However, there is an absence of recognizable soil layers and bioturbation anywhere in the geologic column. So where are the soils after millions of years of exposure as dry land? Obviously, there was not enough time to produce soils. Again, one can reasonably conclude that sediment layers were not exposed to an environment of soil accumulation and plant and animal activity before they were rapidly buried.28
