Why might the earths oceans be described as one huge ocean

It might be described that way because all of the oceans on this planet are connected, therefore form one huge ocean.

This is probably because all the oceans help us by giving rain and all the oceans are connected with each other. Hope this helps you.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
