    […] Blog post about Continents […]

  • Jim 3 years ago

    I can’t believe it. This is the most misleading article from a geography teach I haven’t ever seen. The definition of continent is exactly the opposite.

    There are really just 4 continents in the world:

    America (North and South combined)

      I think this quote says it all: “This is the most misleading article from a geography teach I haven’t ever seen.”

      Sorry to hear you didn’t actually see the article.

      In my opinion, there would be just three large enough landmasses whose continental crusts are independent

      – Euramerafrasia (Europe, America, Africa, Asia, sans Madagascar and Iceland)

      Eurasia and Africa are connected by the Sinai peninsula.
      Eurasia and America’s continental platforms are connected by the Bering strait, whose depth is never more than mere 49 meters.
      Madagascar, Iceland, and lesser islands not laying upon the continental platform do not belong to the continent.

      – Sahul (Australia and New Guinea)

      Australia and New Guinea are conneccted by the Arafura Sea.

      – Antarctica

      There are 6 continents:
      south am.
      north am.

  • Richard Garcia 2 years ago

    I believe in only 4 continents. AfroEurasia, the Americas (as a whole), Australia and Antarctica.

    • Justin 2 years ago

      Believe what you like, but “continent” = continuous land. That ain’t Australia or Antarctica.

      • James 5 months ago

        Your argument ignores the fact that the Americas are also a separate landmass. If Australia can’t be considered a continent because it is isolated from other continents then nor can the Americas. Therefore Eurasia/Africa being the biggest continuous continent is the only continent.
        If you include the Americas, what’s your justification, their size? You have picked an arbitrary size limit then. What is it based on?
        Australia not only has it’s own continental shelf, it has it’s own fricken tectonic plate: https://earthhow.com/7-major-tectonic-plates/ As does Antarctica.
        God help your students if you pass of this nonsense as an education.

    Oh no! Another blow to the status of my beloved country, Australia. So not only are we a small economy with an even smaller population, now we are just a dirty big island and not even the biggest one. Please don’t tell our Prime Minister. Our past ones love to swan about the world stage pretending we are an important and influential country. That’s why we end up in so many awful wars/conflicts that we shouldn’t be in and most Australians hate. 😀

    This is the most scientifically illiterate thing I have read all week. There are 8 lithospheric plates that house individual continental landmasses. Eurasian, North American, Antarctic, South American, Australian, Arabian, and Indian. You should probably take a Geology 101 class, as your understanding of a continental plate (continent) and an island is significantly flawed.

    • Justin 6 months ago

      Hi Bryan,
      Thanks for your kind words. If you look up the word “continent” you’ll find it doesn’t have its origins in plate tectonics. So your argument is incontinent. See what I did there? 🙂

  • Keso 5 months ago

    I believe there are four continents. America, since I believe that North and South America are connected. Afro-Eurasia. Europe is not a continent, it’s connected to Asia. Eurasia is connected to Africa. Australia, it’s not really connected to another continent. Antarctica, which is kind of an exception since there are no countries on Antarctica.

  • ROMAN 5 months ago

    i know only 4 continets and that is Eurasia, Africa,n.America And S.America.

  • Joseph 3 months ago

    First of all Mr, Yee, it looks like you do not even acknowledge the existence of Africa. I would like to suggest that the only real continent id Africa because it has never moved. All others are man made imaginations and creations. It seems when the Europe names it and defines it, it comes into existence!!. This is all mercantilism at work with a world curved out and defined for the benefit of the European. It is true that just as in History, the story of the European’s experience is what we study in most of our disciplines; why not World Geography. Please give me something authentic to think about to debate!!

    What about Plate Tectonics?

    • Justin 1 month ago

      I keep the concepts separate for a few reasons: (1) I’m a geographer, not a geologist; (2) use of the term “continent” predates plate tectonics and continental drift theory; and, (3) no one refers to the Juan de Fuca plate as a continent. I guess I’m more interested in the proper colloquial place-name usage than any effort to pursue a scientifically sound definition. Mostly it just seems clear that neither Europe, Australia nor Antarctica qualify, at least not to the same extent, as “continuous” land masses.

  • Per 1 month ago

    I can’t understand your reasoning. All land masses are islands surrounded by oceans. Have you picked an arbitrary size limit? And if so what is that size limit and how did you come to that conclusion?

    • Justin 1 month ago

      Try looking at a map, buddy. The “continuous” part of continental applies to North & South America, Africa and Eurasia. It doesn’t apply elsewhere.

    Europe is a peninsula in east of Asia. Actually Europe is a Western Asia. Finish! This is an undisputed scientific and geographic reality. The acceptance of Europe as a separate continent is because of Christianity, racism, cultural and social discrimination. For example I am a Turkish. Turks actually is an Eurasian nation like Russians. We are not a Middle Eastern. Our real homeland is Tuva Republic in South Siberia district (Altai Mountains). I mean we are actually South Siberian Nations. We are relative wih Finnish, Estonians, Hungarians (Especially Szekely Turks in Romania), Bulgarians, Kipchaks, Cumans, Tatars, Kazakhs, Karaim Turks in Latvia, Gagauz Turks in Moldova, Crimean Turks in Ukraine etc. We are old nations in the Europe. For example Scythians – Sakha Turks are an old European nations and empires in Europe. Ottoman Empire, Avars, Attila’s Huns, Golden Horde Empires. Who is European or not? The first Turks (Look at Proto-Turks in Chinese History) were a blonde race. There are still blonde Turks today (Kiphcak, Cumans. Gagauzia, Western Thracia, Szekely Turks, some Tatars and Bulgarians). In Europe, Slavic-speaking nations are called Slavic, but the same thing is not said for nations belonging to the same language family as Turkish. NO NOOO TURKS AND FINNISH, ESTONIANS, HUNGARIANS IS NOT RELATIVES. FOR EXAMPLE HUNGARIANS CLOSE TO SLAVS AND GERMAN. YES I SEE… THIS IS FUCKING PAN SLAVISM AND GERMAN AFFECTS ONLY AND WITH THE HELP OF CHRISTIANITY.

    For someone capable of bringing up a provocative and interesting question, you’re sure a douche when people disagree with you.

    • Justin 1 week ago

      Sorry you feel that way Mr. Ear Lobe. Sarcasm occasionally seems overly harsh without the benefit of body language or verbal nuance. And perhaps I get irritated once in a while. On the flip side, I don’t think I called anyone a derogatory name like “douche” so there’s that.
