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.
I heard this from another page on the internet. If you dig 5 miles down starting from the deepest part of the pacific ocean, you will hit the mantle.
Challenger Deep, the deepest known point in the Earth's seabed, is about 36,070 feet below sea level, located at the bottom of the Mariana Trench in the western Pacific Ocean.
The aphotic zone: places where they aren't getting any sunlight.
Oceanic crust is part of the lithosphere and is considered part of the crust. It extends down 7 kilometers, or 4 miles. It is relatively thin in comparison with other layers. It is deep beneath the oceans and is very dense.
About four km down a gold mine shaft in Africa, it simply gets to hot to go any further. The deepest mine is 3.9 KM or 2.4233 miles down.
The coin fell as far down into the well as possible. "Far down", usually neans, the deepest limit. He lives "far down" the street. He lives a long ways down the street.
I believe they were digging to see just how far they could actually dig.
It is 6,000 feet deep at the deepest point.
A) it is. Geothermal energy exploits it. B) Lack of technology. Have you any idea how far above the earth's core we are? * The deepest mine in the world is less than 4 kilometres; * The deepest drilling has reached is 15 kilometres;
At present, the deepest mine is in South Africa, 11,761 ft. In theory, there is no limit. However, as depth increases, so does heat, to the point that conditions are not livable without extreme measures to control it. The weight of the rock above the mine begins to be a problem, since it exceeds the strength of the rock at your working depth, resulting in "rock bursts", where side, roof, or floor may blow out explosively for no reason.
no, because we do not yet have the technology to go down deep enough, and don't have cameras that work well enough when going down that far.
The deepest place on earth is the Mariana trench, which is not something from WWII! It is located north of Paupa New Guiena and south of Japan, located in the far west Pacific Ocean. The trench's deepest point is at 10,916 meters deep, the deepest point in the world known to man and dolphin. The trench also reaches a legnth of 2,550 meters long.
160 km
The Pacific ocean is by far the deepest of the oceans. The Marianas Trench is the deepest place on earth. It is deeper below sea level than Mt Everest is high.
Marianas trench, not very far from Japan, in the Western Pacific.
Definitely! Gold has long been the basis for South Africa's relative prosperity. At least half a million South Africans, including dependents and suppliers, rely on the industry. From ancient times to 1989, the South African mines produced more than 40% of all the gold that had ever been mined. In 1970 South African gold production was 1000 tonnes, then more than 70% of the output of the non-Communist world. South Africa is still the world's largest producer, by far. It has the world's deepest mine, 3585 m below surface at the East Rand mine. The Freegold mine, owned by Anglo American, was until recently the world's most productive gold mine at 115 tonnes a year; and Driefontein Consolidated has produced more than any other gold mine, at 2292 tonnes.
