Rivers dump tons of sediment into the world’s oceans every day. Sedimentologists have researched many of the world’s rivers and calculated how fast the land is disappearing. The average height reduction for all the continents of the world is about 60 millimeters (2.4 inches) per 1,000 years. This equals some 24 million metric tons of sediment per year going into the oceans. If the earth were even only one billion years old, a height of 60 kilometers of continent would have eroded. The earth’s highest mountain, Mount Everest, is only 8.85 kilometers high. Obviously the continents of the world have never been on average over seven times as high as Mount Everest, because that sediment would have had to have gone somewhere. That somewhere is the oceans, which means that the oceans would have had to have initially been correspondingly deeper, and we would today see the ocean floor miles thick in sediment-which is not the case. Also, at this rate of erosion, North America should have been leveled in 10 million years. The Yellow River in China could flatten a plateau as high as Everest in 10 million years. ([Footnote:] Walker, T., “Eroding ages,” Creation Ex Nilho 22(2):18-21, 2000.) Therefore, the earth could not possibly be billions of years old as required by the theory of evolution, or not just the mountains, but every landmass, would have been eroded away and be now covered by the ocean.
[Callout:] If the earth were as old as evolution demands, all land would have eroded into the ocean by now.
