Continents on the northern hemisphere

  1. Mar 31, 2007 #1
    I am supprised and puzzled when my nephew, a 14 year old boy asked me : 'Why most of the continents are on the Northern hemisphere ?'.
    I answered him it is just a coincidence. Could anybody explain if there are any real reasons for that?
    Thanks

    Thank you Bill, it's very nice animation. But frankly I can not find the answer myself.

    The animation shows the continents moving, constantly changing patterns over hundreds of millions of years. At one point they are all jammed together, at another point most of them are in the southern hemisphere. What it shows is that the pattern of the continents isn't permanent. They're still moving around, extremely slowly.
    So it seems you were right, that it's just chance. If he'd been around a couple hundred million years ago (or a couple hundred million years in the future) it would all look different.
