ur q is what is the deepest part of the ocean?and it is the deep sea trench.a deep sea trench is any long narrow steep sided depression in the ocean bottom in which maximum oceanic depths (24,000–36,000 ft, or 7,000–11,000 m) occur.The deepest known depression of this kind is the Mariana Trench. Most trenches occur at subduction zones, where one tectonic plate is thrust under another.\nmariana trench is aSubmarine trench in the floor of the western Pacific Ocean.\n\nIt is the deepest known depression on the surface of the Earth, with a maximum depth of 36,198 ft (11,033 m). The trench extends from southeast of Guam to northwest of the Mariana Islands, a distance of more than 1,580 mi (2,550 km), and has a mean width of 43 mi (69 km.

Currently, the deepest is approximately 6 miles (roughly 10km) - which is about 31000ft.  \n\nRussian scientists dug the deepest hole on the planet in Siberia which bottomed out at about 7.5 miles (12 kilometers) below the surface.

loweest point on earth, no camera has ever been to the bottom, it is believed to be the home of angler fish ang the collisal squid, some believe it is where horshoe crabs go when they are not off new yorks shore

Whenever I am at the beach, I think about the vast world that exists beneath the ocean's surface. Though the marine life is interesting, the ocean floor is what really interests me.  The deepest known spot in the Pacific Ocean is the Marianna Trench, 36,198 feet below sea level. In 1960, the bathyscaph Trieste dove to a record depth in the Trench, plunging to 35,810 feet. The Atlantic Ocean is the shallowest ocean, with an average depth of 11,700 feet. The deepest known spot in the Atlantic Ocean is the Milwaukee Depth, at 27,493 feet below the surface in the Puerto Rico Trench. These trenches exceed the average depth of the ocean floor, reaching deep into the earth's surface.\n\nThat help at all? Next time, just use the Grammar check in your word program.

"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."

How deep is the deepest part of the ocean? Does anything live down there? \n\nWe didn't have to dig very deep to find the answer to this one. We simply typed "deepest part of the ocean" into Yahoo! and uncovered several web pages that answered your question. \nOur first stop was ScienceNet, a British web site that purports to be a one-stop science site. We couldn't dispute that claim after they provided us with the facts of the matter: The Marianas Trench in the Pacific Ocean is 11,033 meters (36,201 feet) below sea level. If Mount Everest were placed inside of this trench, it would disappear. \n\nWe headed back to the search results and saw something that looked very familiar -- our friend Earl, the answer man at Yahooligans!. Turns out Earl had answered the question some time ago and agreed with our earlier finding. He also offered a couple of links to more information on the trench. At Oceanclopedia, we learned that the deepest part of the trench is named Vitjazdepth. The trench was formed when the Pacific plate collided with the Philippine plate, which also resulted in the formation of the nearby island Guam. \n\nTo find out if anything actually lives down there, we swam over to Earth & Sky, a companion site to the popular science radio series. We discovered that plants can't live at such depths because they need sunlight for photosynthesis -- light doesn't penetrate such depths. However, recent photographs from unmanned craft show shrimp-like crustaceans, sea cucumbers, and marine worms. In addition, bacteria flourish on the muddy floors of the trenche

The average depth is  12,881 ft but hte deepest point is  28,231 ft deep  at the Puerto Rico Trench. That is about as accurate as it is going to get.The seafloor is never the same because of it eroding away and seafloor spreading. (just learned about that in school :-D)

The Mariana Trench. It is the deepest known submarine trench, and the deepest location in the Earth's crust itself. Maximum depth 10,911 meters or 35,798 feet below sea level -- just 6,366.4 km from the centre of the Earth.

The temperature of the ocean at depth, anything more than several hundred feet, is 3.98 degrees C.  This is the temperature at which water is densest.\n\nIf any geothermal heat from the sea floor warms the very deepest water, it becomes less dense and rises.  And any shallower water warmed by the sun is too buoyant to descend towards deeper water.  3.98 degrees C is it, all the way to the bottom.

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).

Sea level is considered to be the 0 point from which all land heights and sea bed depths are measured.\nHowever sea level changes over time. \nFactors which effect sea level include gravitational forces and sea level rises due to reduction of ice globally.\n\nSo it doesn't have a depth as it is considered the average point at the surface of the sea. \nEverything below sea level has depth.
