What was found at the bottom of the deepest hole on Earth?
Microscopic plankton fossils were found 6 kilometers (4 mi) below the surface. Another unexpected discovery was a large quantity of hydrogen gas. The drilling mud that flowed out of the hole was described as "boiling" with hydrogen.
How hot is it at the bottom of the Kola Superdeep Borehole?
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.
Why can't we dig to the center of the Earth?
It's the thinnest of three main layers, yet humans have never drilled all the way through it. Then, the mantle makes up a whopping 84% of the planet's volume. At the inner core, you'd have to drill through solid iron. This would be especially difficult because there's near-zero gravity at the core.Aug 6, 2021
Why was the world's deepest hole sealed?
Drilling was stopped in 1992, when the temperature reached 180C (356F). This was twice what was expected at that depth and drilling deeper was no longer possible. Following the collapse of the Soviet Union there was no money to fund such projects and three years later the whole facility was closed down.May 3, 2019
What happens if you dig deep into the Earth?
To make things more difficult, as they drill deeper into the Earth, they'll encounter extreme temperatures, possibly in excess of 1,000 degrees Fahrenheit (538 degrees Celsius), and fantastic amounts of pressure — as much as 4 million pounds per square foot in the vicinity of the mantle.
