I saw a striking demonstration of how moving water sorts materials into layers at the Institute for Creation Research (ICR) near San Diego California. They had a clear plastic tube filled with water and sand and gravel. The tube was mounted so that it could be rotated upside down and the materials would rapidly fall through the water and be sorted into layers.
Rapid Deposition Demonstration

I set up my own larger tube as illustrated in this photo.
I tested with materials of different colors so the sorting shows up more readily. In the hose I put blue aquarium gravel, beach sand (mostly dark), white sand, diatomaceous earth, yellowish hobby train landscape dirt. |

This shows the sequence of how the materials were sorted
out as they rapidly traveled through the long hose and into the clear tube.
(H) After a week, plant life is growing on the top surface. This looks just like the Grand Canyon with all of its layers, and then plants grew on the surface! |

First the materials were placed into a plastic soda bottle with water added. The materials used were dirt from the yard at my house. I also added white and blue aquarium gravel for color. The soda bottle was then frozen for two days. To begin the experiment, the frozen bottle of materials was turned upside down into a full tube of water. |

The ice and materials melted in a little over an hour. Although this is still a short period of time, since all of the materials were not released at the same time, no sorting into layers occurred. From top to bottom you can see the white and blue aquarium gravel and the dirt. |
Another example of slow deposition

In this experiment, the same materials from the fast
sorting tube were slowly deposited manually into the tube of water over
several days. Initially, only about 1/4 teaspoon of materials were
deposited at a time and only once or twice a day. After about 21
days, a full teaspoon was deposited into the tube up to several times a
day.
As you can see, the materials are not sorted out into layers when deposited slowly. What looks like layers at the bottom is actually some mold that starting growing. In fact, if the rock layers we see around the world were deposited slowly, they would have a complete record of plant growth, but they do not. |
