Making Sedimentary Rock (May 19)
Sedimentary rock covers almost 75% of the earth’s surface. Have you ever wondered how sedimentary rock layers were made? Let’s find out. Fill a pint jar with ¼ cup pebbles, ¼ cup of white sand (easier to see with white sand but any sand will do) and ¼ cup of ground-up kitty litter with no additives (kitty litter is bentonite clay). Add water until almost full. Place lid on the jar and shake vigorously to mix. Let the jar stand until all the materials are settled and the water becomes somewhat clear. You should see some results of layering in 15 minutes. It will take several hours for the water to become clear (clay particles settle slowly). Moving water has the ability to separate sediments into layers.
During the Flood of Noah’s day, rocks were ground up in the cataclysmic flood, then transported and laid down. Evolutionists believe that sedimentary layers took millions of years to form, but with your “flood jar,” we observe layers being formed quickly. Sedimentary rock layers are not a monument to time; the rock layers are a monument to the Genesis Flood.
