I usually think of Europe, Asia, Africa, North America, South America, Antartica and Australasia - Arctic cannot be a continent as it has no landmass associated with it. IMO
And someone will explain how Europe, part of the same land mass as Asia,is thought of as a continent. It's just the atttitude of the Ancients that had it so, methinks
Well if you really look at actual landmasses then, IMO it could be Eurasia, Africa, Americas and Antarctica, therefore being four continents - with a proviso of Australia being considered an island by some observers, not a continent..
But I still consider there to be seven, but I am up for a discussion on this.
There's 8 planets. Pluto was downgraded from being a planet due to not having cleared it's neighborhood, if this additional criteria hadn't been added we'd be upto 15+ planets by now with more recent discoveries.
I was taught 7 Seas
Arctic, North Pacific, South Pacific, North Atlantic, South Atlantic, Indian Ocean, Southern Ocean
and 5 Continents
Europe, Asia, Africa, America, Australia
the Arctic and Antarctic were called Polar regions
Craft ,yes that,s right I had forgotten about the 5 rings and the colours of the rings represent a common colour for each of the countries in the Olympic movement.
