Sea (water)

Definition and stakes

Portrait of Jean-Henri Fabre Jean-Henri Fabre,  The Story-book of Science

“ The sea is the common reservoir of the waters. Rivers, springs, fountains, every little brooklet, all come from and all return to it. The water of a dewdrop, the water that circulates in the sap of plants, the water that forms beads of perspiration on our foreheads, all come from the sea and are on their way back to it. However small the little drop, do not fear that it will lose its way. If the arid sand drinks it up, the sun will know how to draw it out again and send it to rejoin the vapor in the atmosphere and, sooner or later, to reënter the ocean-basin. ”

“ When, therefore, we take into consideration the fact that, as a general rule, sea water is, with the exception above stated, everywhere and always the same, and that it can only be made so by being well shaken together, we find grounds on which to base the conjecture that the ocean has its system of circulation, which is well calculated to excite our admiration, for it is as wonderful as the circulation of the blood. ”
