Have you ever noticed how quickly your nails grow? Well, what if we tell you that’s how fast tectonic plates that cover our planet Earth move. Shocked?
So are we!! after seeing the fascinating new video that shows our earth changed over the course of billion years.
This video is one of the most complete as well as fascinating videos of tectonic plate movement ever combined. The scientists had merged a billion years of the movement into a just 40-second video. We can clearly see how those giant slabs of rocks have met over time.
“For the first time a complete model of tectonics has been built, including all the boundaries,” geoscientist Michael Tetley, Ph.D. at the University of Sydney, told Euronews.
“On a human timescale, things move in centimeters per year, but as we can see from the animation, the continents have been everywhere in time. A place like Antarctica that we see as a cold, icy inhospitable place today, actually was once quite a nice holiday destination at the equator.”
We would highly recommend you the video to see with your own eyes the movement and sliding of the plate. You would be shocked to know how recently the countries and continents settled into the positions we see on our map today.
Although these movements and sliding would be a challenge for scientists to understand and predict what will be the pattern of our planet in the future and where we are going to find the metal resources to make sure a clean energy future.
“Planet Earth is incredibly dynamic, with the surface composed of plates that constantly jostle each other in a way unique among the known rocky planets,” says geoscientist Sabin Zahirovic, from the University of Sydney.
“These plates move at the speed fingernails grow, but when a billion years is condensed into 40 seconds a mesmerizing dance is revealed. Oceans open and close, continents disperse and periodically recombine to form immense supercontinents.”
“Our team has created an entirely new model of Earth evolution over the last billion years,” says geoscientist Dietmar Müller, from the University of Sydney.
“Our planet is unique in the way that it hosts life. But this is only possible because geological processes, like plate tectonics, provide a planetary life-support system.”
