The Kola Superdeep Borehole in Russia is the deepest man-made hole on Earth, reaching a depth of around 7.5 miles (12 kilometers). It was drilled to study the Earth's crust and mantle layers. However, no one has ever descended into the Earth's inner core, as it is too hot and inhospitable for humans to access.
The current record is from the Russians, 40,000 feet (7.58 miles). See the related links for the whole story.
Humans have never drilled past the crust into the mantle. We have, however, seen the mantle through "hot spots" like volcanoes where the mantle is closer to the surface.
The deepest borehole ever drilled by humans is the Kola Superdeep Borehole in Russia, reaching a depth of approximately 7.5 miles (12 kilometers). This project was started as a scientific endeavor to better understand the Earth's crust and mantle.
No, scientists have not yet drilled into the Earth's lower mantle. This region of the Earth is located about 400 to 1,800 miles below the surface, making it extremely difficult to reach with current drilling technology. The deepest hole ever drilled, the Kola Superdeep Borehole in Russia, only reached about 7.5 miles deep.
Exxon Mobil drilled an oil well in Russia to a depth of 37,016 feet or over seven miles.
We cannot go to the center of the Earth because of the intense heat and pressure at that depth, which would be extremely dangerous for human survival. Additionally, the technology needed to drill to such depths is not currently available or practical.
The answer is we know what it is because if you Google it up you will find it says the heatness of the earth's inner core is why.
The deepest anyone has drilled into the Earth's crust is approximately 12,262 meters (40,230 feet) at the Kola Superdeep Borehole in Russia, which was completed in 1989. This project aimed to study the Earth's crust and its geological properties, but it only reached a fraction of the way through the crust, as the total thickness can exceed 70 kilometers (about 43 miles) in some regions. Despite its depth, the borehole provided valuable insights into the geology of the crust and the temperature and pressure conditions at such depths.
The Kola Superdeep Borehole is a man-made hole drilled into the Earth's crust, reaching a depth of about 7.5 miles. The Mariana Trench is a natural trench in the ocean floor, known as the deepest point on Earth, reaching a depth of about 36,000 feet. The main difference is that the Kola Superdeep Borehole is on land and drilled by humans, while the Mariana Trench is underwater and formed by natural geological processes.
Lake Baikal its the deepest lake on EARTH!
The crust. Often oceanic crust.Know that man has not yet managed to drill a hole past the crust. The deepest hole ever drilled is the Kola Superdeep Boerhole in Russia, which drilled about 1/3 of the way through the Earth's crust.
