Analysis of the mineral breakdown of dissolved ions in river water by Meybeck [10] indicates that Glaciers produce very finely ground rock flour and, as illustrated by Antarctica and Greenland, add the minutely pulverized material directly to the ocean.

This fine rock flour is dominated by silicate minerals which weather rapidly when added to the ocean.

Global river runoff is about 10% less than global rainfall minus evaporation [19].

This missing water from the continents (approximately L/yr) is believed to be the total ground water seepage from the continents.

First, we list all the known or conjectured inputs and outputs and try to quantify them with the latest data from the scientific literature.

Then, we specify their past behavior in the evolutionary model.

These springs are dominated by water hotter than by way of the axial vents is complicated by the difficulty in measuring the actual vent temperature and calculating the rock to water ratio in these springs.On the next page enter the ABOVE email address, click "SET MY OWN" and amount as 20, your name, message( part of the question) and delivery date (now) and CHECKOUT.

Many scientists became convinced that the earth and the ocean are billions of years old. But there is an indirect test for the hypothesis; we can compare measured input rates with all known or conjectured output rates.

These scientists could no longer endorse Joly's method which they recognized "...leads to the spuriously low geochemical age"[3]. If outputs are considerably lower than inputs at present, then the sea cannot be be in steady state.According to Garrels and Mackenzie [14], Dissolved in the steam that continental volcanoes deliver to the earth's surface are small quantities of Na .
