Radiometric dating methods ppt
According to Garrels and Mackenzie , Dissolved in the steam that continental volcanoes deliver to the earth's surface are small quantities of Na .
Meybeck  calculated the mass delivered from airborne volcanic aerosols to the ocean.
An average Na concentration for this seepage would allow the Na flux to the ocean to be calculated. If we assume that the average ground water has Fifteen years of intense investigations of hot springs on the deep ocean floor have led geochemists to the understanding that large quantities of ocean water are circulated through a significant fracture system in hot sea-floor rocks.
Some of the springs have water hotter than containing significantly more total dissolved solids than seawater.
Thus, we will examine input and output rates carefully. We define the system in question as being the seawater in the ocean basins, not including water trapped in sea-floor sediments.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.

The enormous imbalance shows that the sea should contain much more salt than it does today if the evolutionary model were true. Rubey  were among many who conjectured that in the ocean to remain roughly constant with time. salt must somehow leave the ocean." Those who endorse a 4.5 billion year old earth agree that Joly's 80 to 90 million years is not the age, but the "residence time" for they assert, provides no means for establishing an age for the ocean.A differential equation containing minimum input rates and maximum output rates allows a maximum age of the ocean of to the ocean by rivers has been recognized by scientists for hundreds of years. They affirm, "The 4.5 billion year chronology of earth history is in no way weakened or disqualified by an appeal to the salt content of the terrestrial oceans." But where is the empirical evidence supporting the "steady state" model?
