In this fascinating (and slightly terrifying) infographic, we see the amazing depths of the “known” ocean to scale. As we’ve only mapped about 10% of the world’s oceans, it’s quite possible an even deeper point than the Challenger Deep exists.
The Challenger Deep is the deepest known point in the Earth’s seabed hydrosphere, with a depth of 10,898 to 10,916 m (35,755 to 35,814 ft). It is in the Pacific Ocean, at the southern end of the Mariana Trench. [source]
