    […] Blog post about Continents […]

    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.

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

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

    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.

      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? 🙂
