As we know, the Challenger Deep is located below the western Pacific ocean at the southern end of the Mariana Trench. However, Challenger Deep, currently known as the deepest point in the ocean, it isn’t the deepest point on Earth.
Challenger Deep at a depth of about 26,200 feet is usually referred to as the deepest point on Earth. Well, the truth is, you can rightfully say that it is the deepest known naturally occurring point on the planet.
What’s not often talked about is the existence of an even deeper point on the planet. As explained in the clip below, a Russian bore hole (Kola Superdeep Borehole) was made through the earth that is 10% deeper than the challenger Deep. It took 20 years of drilling to reach a depth of 40,230 feet before the drilling was halted due to unexpectedly high temperatures of around 180 degrees Celsius (356 F).
