Our oceans cover 71% of the Earth surface and there is so much underneath it which we can’t see.
In 2008, NASA released a video showing what the ocean floor looks like once all the water is drained away. Now in an updated version planetary scientist James O’Donoghue edited the timing and added a tracker to show how much water is draining throughout the animation.
The detailed surface underneath the deep blue reveals the continental shelves, land bridges used by early human ancestors to cross over to various continents and the world’s longest mountain ranges.
“I like how this animation reveals that the ocean floor is just as variable and interesting in its geology as the continents,” O’Donoghue told Business Insider.
He added that emptying the seas unearth not only “not only the ocean bottom, but also the ancient story of humanity.”
