Researchers for the first time managed to recreate a complete model of tectonics, including all boundaries.
On a human scale, the movement of tectonic plates seems insignificant – only centimeters per year. But looking at this bizarre dance of giant stone slabs over a billion years is breathtaking, writes Science Alert.
There have been attempts to do something similar before, but today it is one of the most complete models of the movement of tectonic plates ever collected. Scientists have combined the movement of land masses over the past billion years and fit them into a 40-second video that is unlikely to leave anyone indifferent.

Note that the tectonic plates cover the Earth like a mosaic, and move as fast as our nails grow. As their bizarre “dance” plates affect the life of the planet more than we might think – the nature of the tides, the evolution and movement of flora and fauna, volcanic activity, the production of metals and many other equally important processes.
According to geologist Michael Tetley, this is the first complete tectonics model to include all boundaries. 40 seconds of sliding and moving platforms resemble a bizarre dance or a movie plot, where land masses either become close friends, or move away from each other.
Scientists find it surprising how recently some countries and continents “settled” nearby from each other. If you look at this process through the prism of a billion years of movement.
No less surprising is the fact that the now cold and unfriendly Antarctica was once a very attractive and hospitable “resort” on the equator.
< p> According to another geologist from the University of Sydney Sabin Zahirovich, our planet is incredibly dynamic. The surface of the Earth is made up of plates that are constantly touching and receding – a truly unique experience for known rocky planets.
Scientists note that the farther back in the past, the more difficult it is to learn about the movement of plates. It still remains a mystery how they were first formed and when it happened. Geologists agree that the new model of tectonics will not only shed light on the ancient past of the Earth, but will also allow us to make predictions about how habitable our planet will be in the future.
