6. Farly scientists tried to determine the age of Zarth usinis a variety of methods. After fomond
Halley proposed that seawater is salty because rivers tansport dissolved ions (from the weathering
of continental rocks) to the oceans, John Joly sugessted that the age of the Earth could be easily
calculated if the amount of sait in the ocean and the rate at which salt is added by the tivers each
year is known, (10 pts) a. Calculate the age of the Earth using the following facts. Your answer
should be given as a range between two values. Be careful with units and decimal placest show
your work for full credit. - The volume of the oceans is 1,370,000,000km1 - 1% of seawater, by
volume, is sodium. - The annual volume of water entering the oceans from rivers is 30,000km ?. -
River water contains between 3 and 11 parts per million (ppm) sodium (i.e., 0.0000030.000011) b.
What is the actual age of Earth? How does your answer compare to this? If these answers vary
significantly, explain possible sources of error that contribute to this difference (one paragraph will
suffice)..
