plate tectonics

Greater thicknesses of sediments are encountered on the continental shelves and slopes.

the amount of sediment on the floor of the ocean increase in thickness from the mid-atlantic ridges to million of years worth near america and europe..that is consistent with plate tectonics

The present topographic continents above sea level have a volume of about 30.4 million cubic miles and a mass of about 383 million billion tons. If the present continents were eroded to sea level, about 383 million billion tons of sediment would be deposited on the ocean floor. This mass is a little less than half the mass of sediment present in today's ocean. Stated another way, it would only take the erosion of twice our present continental mass to produce today's mass of ocean sediments!

but continents have “grown” in the past..with lava flows, plate tectonics, etc..erosion rates are higher now than they have been in the past because of the the topography of the continents..they are more rugged and mountainous than usual, and that speeds up erosion

Careful study of modern rivers on a world-wide scale shows that vast quantities of rock are being transported to the ocean. Suspended sediment, small rock particles which are carried along by river turbulence, comprise the bulk of sediment added to the ocean. The best estimate from river data suggests that 20.2 billion tons of suspended sediment enter the ocean each year.4 Rivers also carry dissolved chemical substances into the ocean. The chemicals are mostly bicarbonate, silica, and salts which comprise about 4.6 billion tons of sediment added to the ocean each year.5

Glaciers at higher latitudes are presently breaking apart and adding icebergs to the ocean.

have glaciers been breaking apart forever?..no

When the ice melts, the entrapped sediments are deposited on the sea floor. Ice appears to be delivering about 2.2 billion tons of sediment to the ocean each year.

that data doesnt mean a whole lot since glaciers have been receding for about 10,000 years

The seashore is constantly being worn by waves which deliver sediment to the sea. A good estimate suggests that marine erosion adds 0.28 billion tons of sediment annually.

but land masses expand..on hawaii, a few years ago, the island volcano erupted and added something like 11 square miles to the island..(also, there is an new island forming south of hawaii, and will be a true island in about 50,000 years)

How long would it take to deliver the present continents to the ocean if the present rate of erosion continues?

but the present rate of erosion will not continue

There are about 30.4 million cubic miles of continental crust above sea level with a mass of 383 million billion tons. To calculate the amount of time required to deliver the present continents to the ocean we need only divide the mass of continents above sea level by the annual rate of erosion. The calculation would be:

The continents are being denuded at a rate that could level them in a mere 14 million years!

if the rate were continuous..however, it isnt..the continents will get less rugged and mountainous someday, and the erosion rates will go down..also, there could be a time of higher volcanic activity, that can and will cause more land to be formed

Yet, evolutionary-uniformitarian geologists feel certain that the continents have existed for at least 1 billion years. During this supposed interval of time the present continents could have been eroded over 70 times! Yet-miracle of miracles-the continents are still here and do not appear to have been eroded even one time!

if the erosion rates were continuous, which they are not

Even though the continents could be eroded and transported to the ocean in just 14 million years, assume that some mysterious uplifting process continues to raise the continents as they are eroding. How much sediment would form at present rates of erosion in one billion years? The answer is found by multiplying the annual rate of addition of sediments to the ocean (27.5 billion tons per year) by the alleged evolutionary age of the ocean (1 billion years). During 1 billion years 27.5 billion billion tons of sediment would be produced. This is enough to cover the entire ocean floor with 97,500 feet (18.5 miles) of sediment!

thats assuming that there were no plate tectonics, and that rates of sediments entering and leaving the ocean remained the same

if we assume the present rate of erosion and exposed continental volumes to have existed over the evolutionist’s supposed 1 billion year history of the world ocean, we would expect a staggering layer of sediment almost 100,000 feet thick to cover the sea floor today!

name one person, other than the creationists, that claim that any of that is constant

Since such a monumental layer does not exist, it seems that evolutionists have grossly overestimated the age of the world ocean.

no it doesnt, because no evolutionist claims that the present rate of erosion has been around forever

Some of the oldest ocean sediments appear to have been deposited rapidly from debris-laden water immediately after the Flood.

how rapidly?..rapidly as in a human lifetime(which i would say to be less than a year) or rapidly in the sense that the earth has been around for 4.5 billion years, so rapidly would mean possibly a few thousand years

If the world ocean is a billion years old, there should be an enormous quantity of ocean sediments.

no, there shouldnt..because the rates of sediment entering and leaving the ocean varies

Yet, even the evolutionist is aware of the scarcity of sediments. What would be his rebuttal to the arguments presented so far?

the rebuttal is what i wrote above..also, there are plate tectonics

If the major quantity of sediment is not being removed from the ocean by uplifting, then the evolutionist must suppose some process which plunges deep ocean sediments into the depths of the earth! The favorite method is called "sea floor spreading," and suggests that the ocean floor is like a conveyor belt. Ocean crust is assumed to form continuously at the mid ocean ridges, then it accumulates sediments as it slowly moves away from the ridge, and finally both crust and sediments are destroyed by re-melting when dragged below ocean trenches. The best estimates by evolutionary-uniformitarian geologists suggest that about 2.75 billion tons of sediment per year are being destroyed by sea floor spreading. This rate is only one tenth of the modern rate of addition of sediments to the ocean. Stated another way, ocean sediments are forming today at a rate ten times faster than they are being destroyed by sea spreading!

but that doesnt mean that was true years ago
