Canyons can be found under the sea at the end of many major world rivers, including the Congo, Amazon, Ganges, and Hudson.  They extend for thousands of miles underwater, thousands of feet under the sea; they are as deep as the Grand Canyon in places, and although not well understood by the mainstream scientific community, they are generally understood to have developed when sea-levels were significantly lower than today. Flood geologists argue that as the continents divided and the flood subsided, these major rivers drained the new continents, and the water flowed into the new low-lying areas, which would fill to become seas, leaving the sediments to dry out of their [[liquefaction|liquefied]] state.

Secular scientists respond by citing sediment flows, which have the ability to act as a stream of sand, that has the ability to over millions of years, erode the underwater continental shelf.
