Where is the sediment? This image depicts a tranquil sea. Nothing in the young-earth flood geology literature suggests a placid flood covering the earth. If the Ark has already been raised above the mountain tops, as shown in the image, how could 20,000 feet of sediment be deposited onto the pre-flood land from clear water? Small particulates in the water column could not have settled out in enough time for the waters to ever have been clear during the Flood.
