The Deepest Point on Earth Is Not Challenger Deep?

Challenger Deep is the deepest known point in the ocean, reaching about 26,200 feet. However, it is not the deepest point on Earth. The Kola Superdeep Borehole in Russia goes even deeper, measuring 40,230 feet. Drilling for this borehole took 20 years and stopped due to high temperatures. This highlights that the depths of our planet are more complex than we often realize.
