Half the water on earth is older than the solar system itself. whoa.

We are stardust, we are carbon, we are billion year old carbon..We are older than the solar system.

That's interesting. Where does "residence time" (Lake Retention Time) for a lake come into play. That's the time it takes for every drop of water in a body of lake water to exit and be replaced... Or, from what I inderstand

 

I didn't read the article yet. Examples of residence time for the Great Lakes is:

 

2.6=Erie

6=Ontario

22=Huron

99=Michigan

191=Superior

1) Actually, that's the time it takes for any given water molecule to have a 50% chance of exiting the lake.

 

2) What does that have to do with the original article?
