>For example the argument of the continents surrounded by water does not hold any of it, as Europe would not be a continent, America would be only one; or how would you seriously consider the Caribbean islands or other islands on Oceania, even Greenland to be part of any continent; they are, like most islands I can think of, surrounded by water. In the end, is just convention that has little or no facts to support it. (Most of those claims can be seen here http://www.worldatlas.com/aatlas/infopage/contnent.htm) And the funny thing from that link is that they say "Many modern atlases and geography experts now consider the long-established continent of Australia to be better defined as Australia/Oceania," is funny because as old as I am, we never studied Australia as a continent, it was always Oceania)

As old as I am Australia was a continent and the term Oceania was never mentioned in World Geography.
