Is Mariana Trench deeper than Challenger Deep?
In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth. The Challenger Deep is nearly three times deeper than that.
Is there anything deeper than Challenger Deep?
It’s the Kola Superdeep Borehole, 12,262 meters deep, around 1300m deeper than the Challenger Deep in the Mariana Trench.
What is the temperature at the bottom of Kola Superdeep Borehole?
356 °F
While the temperature gradient conformed to predictions down to a depth of about 10,000 feet, temperatures after this point increased at a higher rate until they reached 180 °C (or 356 °F) at the bottom of the hole.
What did Divers find in the Great Blue Hole?
As the crew started, they found the usual suspects: reef sharks, turtles, and giant corals. But as they pushed 90 meters, life started to vanish. The culprit was a thick layer of toxic hydrogen sulfide spanning the width of the entire sinkhole like a floating blanket.
What is the deepest man made hole on Earth?
