Sea/Ocean Water

[YT2095]

Does anyone actualy KNOW how our seas and oceans became salty? and why mostly Sodium Chloride?

 

(I`ve heard several ideas, but each seems to have a flaw appart from the asteroid one, that only suffers from a lack of evidence).

 

anyone?

I seem to recall reading a thread about this on another forum somewhere. I'll see if I can dig it up.

Interesting, and thnx

I find it quite surprising however the Chlorine to Sulpher ratio.

I`de have expected greater sulpher in the form of sodium sulphate as a result of volcanic activity, and the chlorine quantities seem huge alone even taken without comparison to the others.

 

it`s equaly interesting to note (not from the above url) that human blood salinity is roughly equal to that of the oceans. I`m sure Glider will know more.

when it`s said that we evolved out of the oceans, it surely adds a little more weight to the argument

Cytoplasm and interstitial fluid are also roughly the same. We evolved in the sea, and that environment proved highly condusive to the chemical processes required for life. Basically, whilst we evolved and left the sea to colonise dry land, the basic environmental requirements for life remained the same, so we took that environment with us, enclosed in our cells and tissues.
