Hello,

(Small Talk Mode).....How are you ?..I'm fine  !..a bit tired..hope you're well !!



Is the amount of water in/on the Earth changing in quantity at all ?


At one point there was none yes ?...now we have icy places...liquidy places and gassy places too !!

Does any evaporate out to space ?...if so ...is there a mechanism which replaces it ?

whajafink ?

This is actually more of a planetary science/astronomy question.  I believe that most of the water came from outer space, in the form of meteors and comets.

Correctamundo, Dr.D. - There are enough icy meteorites falling into (or hitting, however you wish to word it) to raise sea level about an inch a year.

I know I read this on the NASA site (100% sure)and I think I also recall a reference to it in an article on the rates of sediment formation in (I think) the Journal of Sedimentary Petrology (10-15% sure)??? but my memory is full of holes.

So are you asking, when it evaporates here does it go further up into the atmosphere then just the clouds?
