where is The World's Deepest Hole?

The Mariana Trench (or Marianas Trench) is the deepest known submarine trench, and the deepest location in the Earth's crust itself. It is located in the floor of the western North Pacific Ocean, to the east of the Mariana Islands at 11°21′N 142°12′E, which is near Guam. The trench is the boundary where two tectonic plates meet, a subduction zone where the Pacific Plate is being subducted under the Philippine Plate. The bottom of the trench is further below sea level than Mount Everest is above sea level.\n\nThe trench has a maximum depth of 10,911 m (35,798 feet) below sea level. Taking into account its latitude and the Earth's equatorial bulge, this puts it at 6,366.4 km from the centre of the Earth. The Arctic Ocean, on the other hand, is 4-4.5 km deep, which would put its floor at ~6,352.8 km from the Earth's centre, 13.6 km closer.\n\nIt was first surveyed in 1951 by the British navy vessel, Challenger II, which gave its name to the deepest part of the trench, the Challenger Deep. Using echo sounding, the Challenger II measured a depth of 5,960 fathoms (10,900 m) at 11°19′N 142°15′E. This sounding was repeatedly made using earphones to hear the return of the signal as the stylus passed across the graduated depth scale, whilst the timing of the speed of the echo-sounding machine, a necessary part of the process, was made with a hand held stopwatch. For these reasons it was considered prudent to subtract one scale division (of 20 fm) when officially reporting a new greatest depth of 5,940 fm (10,863 m).\n\nIn 1957, the Russian vessel Vityaz reported a depth of 11,034 m (36,201 ft), dubbed the Mariana Hollow; this measurement has never been replicated and is not considered accurate. In 1962 the M.V. Spencer F. Baird recorded a greatest depth of 10,915 m (35,810 ft). In 1984 the Japanese sent the Takuyo, a highly specialized survey vessel out to the Mariana Trench and collected data using a narrow, multi-beam echo sounder; they reported a maximum depth of 11,040.4 m1 (this is also reported as 10,920±10 m 2). The most accurate measurement on record was taken by another Japanese probe, Kaiko, on March 24, 1995: 10,911 m (35,798 ft) 3.\n\n \nJanuary 23, 1960: Just before the diveIn an unprecedented dive, the U.S. Navy bathyscaphe Trieste reached the bottom at 1:06 pm on January 23, 1960 with U.S. Navy Lt. Don Walsh and Jacques Piccard. Iron shot was used for ballast, with gasoline for buoyancy. The onboard systems indicated a depth of 37,800 ft (11,521 m), but this was later revised to 35,813 ft (10,916 m). At the bottom Walsh and Piccard were surprised to discover soles or flounder about one foot (30 cm) long, as well as shrimp. According to Piccard, "The bottom appeared light and clear, a waste of firm diatomaceous ooze".\n\nAt the bottom of the Mariana Trench, water exerts a pressure of 1086 bar (108.6 MPa or 15,751 psi).

The average depth of the oceans is about five times the average elevation of the land. In general, the continents stand about three miles above the ocean floor. According to the National Geographic Atlas, the deepest-known part of the ocean measures [10,924] meters (35,839 feet), in the Marianas Trench near Guam. If the world's highest mountain, Mount Everest (29,141 feet), were to be placed into this trench, it would be covered by over 1.25 miles of water.

At its deepest? About 11,000 meters deep. On average its about several thousand meters deep.

the deepset point on earth is calld the MARIANA TRENCH, it is located in pacific ocean and is some where around 11300 metres deep. and taht is more than the tallest point the mount everest which is only 8848m high. cheers

rekn may be right, but from what information we have, including satellite surveys, the deepest knows ocean is the pacific ocean with an average depth of 4270 m (14000 ft). the deepest point on the pacific is the mariana trench at 10 911 metres (35,797 ft) below sea level, it is also the deepest know point on the surface of earth

I'm not getting the same measurment as you (I don't think), but I hope that this helps you. It's from the Guinness World Records site.\n\nThe deepest part of the ocean was first pinpointed in 1951 by HM Survey Ship Challenger in the Marianas Trench in the Pacific Ocean. On January 23, 1960, the US Navy Trieste vessel descended to the bottom of the Pacific Ocean, and on March 24, 1995, the Japanese probe Kaiko recorded a depth of 10,911 m (35,797 ft), the most accurate measurement yet taken.\n\nHope it helps. :)

The deepest known point on Earth is at the bottom of the Mariana Trench, a depression in the floor of the western Pacific Ocean, just east of the Mariana Islands.\n\nThis underwater gorge plunges to a depth of nearly 7 miles! It is deeper than Mt. Everest is tall.\n\nKaiko entered the record books in 1995 when it dived almost 11,000 meters to the bottom of Challenger Deep -- the world's deepest stretch of ocean -- in the Maruyama Trench, near Guam, in the western Pacific. 2nd link:\n\n\nSee link:

Drilling into the earth is done for a number of reasons. Some are exploratory, many are for oil, some for water, some for mining purposes, and others for various reasons. As we explore the layers of the earth, we uncover many things and have a need to dig deeper into the earth into uncharted regions, not knowing what we will find.\n\nThe deepest drilling ever done by mankind is the drilling that has taken place on the Kola Peninsula in Russia. This drilling started in 1970 and had reached a depth of 12,262 meters, in 1994. The drilling itself was done differently in the Kola Peninsula. The entire drill itself was not rotated; only the drill bit was turned by the flow of drilling mud.\n\nThe Kola Peninsula drill's goal drilling depth is 15,000 meters. At this depth it is expected to be 300 degrees Celsius or higher, too high of a temperature for the drill to operate at. Another drilling worth mentioning has been started in the Caspian Sea. This drill also shares the same goal depth as the drilling at the Kola Peninsula. Aside from drillings for research, a noteworthy drilling is the Bertha Rogers well in Oklahoma, Texas, which is a 9,583 m (31,441 ft) deep gas well. This was the previous world record holder prior to the drilling in the Kola Peninsula. The well was started in 1974 and continued until it struck molten sulfur at its final depth.

The deepest place is near the Mariana Islands in the Pacific. The water is over 36,000 feet deep in the Mariana Trench. That's over 7 miles deep. Mount Everest is only 6 miles high!

The deepest part of the ocean is the Mariana Trench in the South Pacific Ocean. The depth of the ocean here is about 35, 839 feet (10,927 meters).

The worlds deepest cave is currently the Krubera (Voronja) Cave in the country of Abkhazia. The cave has been mapped to a depth of 7021 feet (2140 meters).\n\nSistema Cheve in Mexico is only number nine on the list at 4869 feet. \n\nThe world's deepest cave list (last update 3/10/06) is maintained by a member of the National Speleological Society and can be found here:\nhttp://www.caverbob.com/wdeep.htm

I figure the only places left are some of the more inaccesable dense rainforests of the South American continent. But the other possibility would be underground, cavers or speliologists have been trying to probe the depths of the earth by exploring underground caves and tunnels as well as flooded waterwaters to see how far they can go below the earth. That besides the oceans must be the last place where humans have never ever set foot on in this earth.

The Red Sea is not the lowest point on earth.  However, I do believe that you are thinking of the Dead Sea!  The Dead Sea is one of the lowest points on earth, and water that flows into it does not flow back out (it is called the dead see because it is so salty that no living thing can survive in it.  It's so salty that it actually makes it easier to float!)  The actual lowest point on earth is Mariana's trench, which is in the pacific ocean near Southeast Asia.  I believe that the depth is around 28000 feet (the last time I knew, no submarine had ever touched the bottom, but they did come to within about 3 feet of the bottom).  I hope that that sufficiently answered your question.
