Using information from inside the rocks on Earth's surface, we have reconstructed the plate tectonics of the planet over the last 1.8 billion years.

    Poor cameraman stuck in space for 1.8 billion years Guess it’s true that the cameraman never dies.

    I’m a bit confused by the video reconstruction I’m not going to lie: https://youtu.be/_LJG68AmZxI

      What’s the confusion? Maybe I can help.

      Did you realize it was working backwards?

        Ohhhhh yes that’s it. It was also so much more movement than I was expecting! I was expecting us to go from pangea glob to continents and then some shifty shifty but man those tectonics were BUSY.

          Lots and lots of convection in that mantle.

          Pangaea is only the most recent supercontinent, and therefore the most known. there are believed to be several more iterations in this cycle of combining and breaking up large landmasses.

        The working backwards was interesting, but also fascinating how the ratio of land to sea was so much different at the start.

      Is the land sea ratio due primarily to sea level changes?
