A Young-Earth Claim: If the earth was billions of years old, there would be more salt in the sea.

Here are excerpts from three lists of young-earth claims:

Jonathan Sarfati — Salt is pouring into the sea much faster than it is escaping.  The sea is not nearly salty enough for this to have been happening for billions of years.  Even granting generous assumptions to evolutionists, the seas could not be more than 62 million years old — far younger than the billions of years believed by evolutionists.  Again, this indicates a maximum age, not the actual age.[19]

Russell Humphreys — 5. Not enough sodium in the sea:  Every year, rivers[8] and other sources[9] dump over 450 million tons of sodium into the ocean.  Only 27% of this sodium manages to get back out of the sea each year.[9,10]  As far as anyone knows, the remainder simply accumulates in the ocean.  If the sea had no sodium to start with, it would have accumulated its present amount in less than 42 million years at today's input and output rates.[10]  This is much less than the evolutionary age of the ocean, three billion years.  The usual reply to this discrepancy is that past sodium inputs must have been less and outputs greater.  However, calculations that are as generous as possible to evolutionary scenarios still give a maximum age of only 62 million years.[10]  Calculations[11] for many other seawater elements give much younger ages for the ocean.

Carl Wieland — 5) The oceans are nowhere near salty enough.  Each year, the world’s rivers and underground streams add millions of tonnes of salt to the sea, and only a fraction of this goes back onto the land.  Using the most favourable possible assumptions for long-agers, the absolute maximum age of the oceans is only a tiny fraction of their assumed billions-of-years age.[7]
