The deepest man-made borehole in the world is the Kola Superdeep Borehole (Russia, 1989) at 12,262 meters (7.6 miles). The deepest natural ocean depth is about 6.8 miles (11000 meters), in the Marianas Trench near Guam.
The deepest man-made hole in the Earth is located in the Kola Peninsula in northwestern Russia. The depth achieved from the surface was 12,262 meters, roughly 7.5 miles. The 9" bore hole was created by a rotating bit spun by the pumping of drilling mud. Unexpectedly high temperatures caused the stoppage of the drilling in 1994, 24 years after drilling was started. The goal of the Russians was to drill to the Moho, the boundary between the crust and the mantle, but the goal was not reached.
See the link below for additional very interesting information on the project.
The deepest point in any ocean is the Mariana Trench (aka Challenger Deep) in the western Pacific Ocean at 11,033 metres deep.
The Kola Superdeep Borehole is a man made hole that is the deepest on earth. In 2007 it reached a depth of 40,230 feet or 12,262 meters. It is located in Russia on the Kola Peninsula.
It would be in Russia on there Kola Peninsula. It is about 40,000 feet deep. They have been drilling since the 1970s.
Ummm.......lets say "why dont u go explore it and tell us?"
The deepest hole drilled into the crust of the earth is 7 miles (12 km.) deep. The hole is on the Kola Peninsula in the USSR
The Congo River in Africa is the deepest river channel (720 ft deep). The Challenger Deep, part of the Marianas Trench in the pacific Ocean, is the deepest sea channel, at 36,197 feet.
Challenger deep
In the Heart of the Deep Deep South
This can be answered in two ways.Man has gone "in person" as deep as the deepest mine, TauTona in Carletonville, South Africa at 3.9 kilometres.Boreholes have been made even deeper.The present holder of this record is the Kola Superdeep Borehole in Russia. It reached 12.262 kilometres in 1989.
About 70km , that is the deepest level of earth crust.
About 50ft
By "biggest" do you mean largest in volume, or simply the deepest? The deepest hole yet dug is called the Kola Borehole and is a bit over 40,000 feet (12,262 meters) deep.
That is hard to say because not all holes are even seen. The deepest hole was probably dug by some sort of burrowing animal or insect.
The superlative form of the word "deep" is "deepest".
The deepest ocean is 36,200ft deep
The Pacific Ocean has the deepest point in the Challanger Deep.
The merced river is about 5 ft deep at its deepest point.
Pretty Deep.
23cm deep
That is the correct spelling of "deepest" (most deep, or innermost).
the worlds deepest bunker is at the Awana Kijal golf course in Malaysia I have played the 18 hole beach front golf course a number of times now and it is claimed to be the deepest at 15m deep, it also doubles as a water hazard when the tide is in!
The second deepest "hole" after the Marianas trench is the Philippine Trench. Once thought to be deepest until further measurements were made in the Marianas trench.
