It has been calculated from the combined effects of suspended particles and dissolved materials removed by rivers that the surface of the United States is being stripped away at an average rate of one foot in 9000 years. Other materials in the stream and riverbeds (i.e. pebbles and particles which are rolled , slid, and moved bodily along the bottom by currents) cannot be measured and are therefore not included, leaving a conservative calculation. For the 1,265,000 square miles in the Mississippi River drainage basin, the estimate is one foot per 5000 to 6000 years. Assuming that factors accelerating the rate (higher average temperature and rainfall) would be balanced by factors slowing it down (periods of drought and areas of vegetation cover) at the minimal average present-day rate of 1 foot per 9000 years, every trace of land would have washed into the oceans many times during the 2 billion or more years that life is supposed to have been present on the planet. At this slow average rate more than 42 vertical miles would be stripped off the land. Even though the seas are a little more than twice as extensive as present land area, the deposited sediments should have caused the oceans to rise nearly 18 miles, making a total of sixty miles the continents would have sunk in relation to sea level. Your are going to need to develop a theory of intermittent land uplift and/or sea bottom depression or formation to counterbalance the leveling effects of erosion and deposition. The average altitude of the continents is only a little more than one half mile above sea level, or three miles above the average sea bottom depth. During a 2 billion year period, Mount Everest, it it were to escape eventual disappearance beneath a shoreless ocean, for example, would have to be re-elevated to its present height more than ten times. At the present average elevation of continents, this figure would be increased to 120 times, all within a time span less than half of the estimated age of the planet and less than two thirds of the time often speculated that habitats suitable for life existed. Furthermore, the erosion rate used for these calculations is far slower than is evidently necessary to account for the high quality of fossil preservation existing in many rock strata. To be preserved as fossils, most animals and plants have to be covered quite rapidly or they disintegrate, leaving no trace. Lief Sorensen Hewlett Packard Co.
