    Continental Fit Continental Fit Presentation Transcript

    • CONTINENTAL FIT
    • Albert Wegner
      His theory was that the continents fit together like puzzle pieces-also known as continental fit.
    • Back in the 60’s…
      It was discovered that south America and Africa fit together better if you connected them at the eastern border of south America and Africa western border then they’d fit like a puzzle piece.
    • Even though…
      South America and Africa were connected, Asia was still conjoined to Africa. So it looked like this:
    • 225 million years ago…
      Australia was connected to Antarctica, and stayed connected up to 65 million years ago.
      Shortly after the separation, Australia started to rotate.
    • North America's eastern border used to be connected to Europe 65 million years in the cretaceous period.
    • India was once connected to Africa’s Eastern Border. It drifted north colliding into Asia creating the Himalayas.
    • This piece of evidence…
      The most important piece. You don’t even need a text book to or computer. All you need is a world map. Its obvious, it fits like a puzzle!
