Kola Super-Deep
Borehole:
Relating to the vast universe our earth is a small point of
creation on which we are living. Geography is the subject that gives you the
knowledge about the Earth and much more about the planets. There are many
secrets obtained from the surface of the Earth.
The scientists decided to dig a hole of about 15,000 meters
below the surface of the earth to find what is inside the globe. While digging
the hole, a strange thing happened, the hole was not able to pass through
12,262 meters or 40,230 feet deep. This activity took place in the year 1989.
After this, the scientist named the core of the earth as the ‘Door to Hell.’
The ‘Door to Hell’ took 26 years to be dug. It is the
deepest unnatural hole on the entire earth. The Kola Borehole is located in
Murmansk Oblast, Russia. The Kola Borehole is assumed to be the deepest hole
than the ocean depth. The ocean covers 70% of the earth, but scientist managed
to reach up to 5% only.
The scientist was not able to dig further because of the
high temperature. They thought the temperature would be only 100 degrees
Celsius, but while reaching 12,262 meters, they found that the temperature was
about 180 degrees Celsius.
After the digging process of 26 years, they found a lot of
underground water in Kola Super-Deep Borehole. Experts identified hot
mineralized water and also gases like helium, hydrogen, nitrogen, and even
carbon dioxide (from microbes) was present in the hole. According to the
scientist at 9,000 meters, they found granite. Hence, they thought basalt will
also be present with granite, but surprisingly there was no basalt.
The project came to end in 2005. A bolted metal cap remains
in the project area to cover the hole. You should imagine, what will happen if
they would have dug deeper. May be, that will be the next step for scientists
to know the earth completely.
