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 k1 (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\nOn November 3rd, 2005, Michael Milord, a sixth-grader from Admiral Farragut Academy, discovered, using Google Earth [1](a computer program that uses satellite imagery in 3D), what he called the “Milord Fist”. Dr. Frank Muller-Karger, USF, College of Marine Science said [2]“The formation Michael noticed is the Mariana Basin, I am sure nobody has seen the similarity between “Milord Fist” and this huge system of submarine ridges, mountains and deep trenches," he said.\n\nAt the bottom of the Mariana Trench, water exerts a pressure of 1086 bar (108.6 MPa or 15,751 psi).

The deepest point in the ocean is the Mariana Trench located in the Pacific Ocean near the Northern Mariana Islands. It has a maximum depth of 10,923 m (35,838 ft) [2]. It was fully surveyed in 1951 by the British naval vessel, "Challenger II" which gave its name to the deepest part of the trench, the "Challenger Deep".\n\nMuch of the bottom of the world's oceans is unexplored and unmapped. A global image of many underwater features larger than 10 km was created in 1995 based on gravitational distortions of the nearby sea surface.

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:

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, near Guam.\n\n[edit]\nDescription\nThe 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 (Challenger Deep) is farther below sea level than Mount Everest is above it. The trench has a maximum depth of 10,911 meters (35,798 ft) below sea level. Taking into account its latitude and the Earth's equatorial bulge, this puts it at 6,366.4 kilometers (3955.9 mi) from the centre of the Earth. The Arctic Ocean, on the other hand, is about 4,500 meters (14,800 ft) deep, which would put its floor at 6,353 kilometers (3947 mi) from the Earth's center, some 13 kilometers (8.5 mi) closer.\n\n[edit]\nExploration\nThe trench was first surveyed in 1951 by the Royal Navy vessel Challenger II, which gave its name to the deepest part of the trench, the Challenger Deep.

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

well, the deepest trench on the earth is 11,034 meters (about 30K feet).. I imagine the abyss being /infinitely/ deep.

The crust but more specifically the lithospheric plates.\n\nThe lithosphere is divided into 7 major plates and about 7 minor ones. The major ones contain the continents.\n\nThese plates move in response to the convection of molten material in the mantle. As the molten rock circulates, it pulls lithospheric plates along like they were on a conveyor belt.\n\nThe crust floats atop the molten rock below b/c it is less dense.

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!

46.6% of the crust is oxygen

earth of course......\nthere is a layer in our blue planet called the mantle which lies between the outer crust and the core.. its the biggest layer even...

No we don't have the ability now, not only is the temperature too great, there is way too much pressure for us to overcome. It would crush anything significant before we got to far. \n\nThe farthest down that we have been is only a few thousand km, and that with a tiny drill.\n\nThe deepest holes in the crust are natural. Volcanoes bring up material from tens of km depth. The crust thickness averages about 18 miles (30 kilometers) under the continents, but is only about 3 miles (5 kilometers) under the oceans. It is light and brittle and can break. \n\nHere is a great article that explains a lot:\nhttp://www.livescience.com/technology/050407_earth_drill.html\n\nThe reason we explore space more, is because not only is it easier to accomplish, but it is also far safer and less costly. I agree though that exploring below the Earth can be quite rewarding, but we simply can't do it as of now.

The Philippine Trench is a submarine trench to the east of the Philippine islands. It stretches with a length of approximately 1,320 km and a width of round about 30 km from the northeast top of Luzon up to the Indonesian island of Malacca Halmahera. Its deepest point, the Galathea Depth, has a depth of 10,540 meters.\n\nUntil 1970, the Philippine Trench was regarded as the deepest point of the earth. Since then, deeper trenches have been discovered, including the Mariana Trench (11,034 meters), the Tonga Trench (10,882 meters) and the Kuril Trench (10,542 meters).
