where is the marina trench?

"The Mariana Trench is located in the Pacific Ocean, just east of the 14 Mariana Islands (11"21' North latitude and 142" 12' East longitude ) near Japan.   As you probably already know, it is the deepest part of the earth's oceans, and the deepest location of the earth itself.  It was created by ocean-to-ocean subduction, a phenomena in which a plate topped by oceanic crust is subducted beneath another plate topped by oceanic crust."

Bay of bengal.\nIts okay i can help you in that .as i know about this place and live near to India (Pakistan).\nfor more information\ncheck this site\nhttp://en.wikipedia.org/wiki/Bay_of_bengal

In San Pedro, California there is a bunch of tunnels that were dug out during world war two.  There is a whole underground world in Long Beach from the 1920,s  an old mall use to be down there near cherry and ocean blvd.  The new Alameda Corridor at the harbor supposedly has tunnels for trucks to drive through.  There is suppose to be tunnels all the way to Mexico.  Colorado has some interesting tunnels, sometimes you can find them on the web, sometimes you can't.  USC has tunnels under it too.  It's a very wierd world we live in.

The Bathosphere was developed by Otis Barton and William Beebee in 1930.\n\nIn 1932 it set a record depth of 3,028 feet.  The record stood for 15 years.

According to Wikipedia:\n\n| The trench is the boundary where two tectonic \n| plates meet, a subduction zone where the Pacific \n| Plate is being subducted under the Philippine Plate.\n\nThe force of the one Pacific plate pushing/pulling under the other plate is causing the rift.

The deepest part of the Oceans is the Marianas Trench (mare-ee-aahn-uss), NOT the Mariana Trench. No human has been able to penetrate that depth of the ocean yet, but i imagine it is only a matter of time until someone does. After the deepest part of the ocean, i guess it is outer space next.

Aside from the guy from a different planet, you're all right.  Challenger Deep is the deepest point of the Mariana Trench in the Pacific Ocean.

It's Challenger Deep : the deepest part part of the Mariana trench in the Pacific Ocean.\n\nIt's 10 900 metres deep

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  (35,838 ft) 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".Much 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.

I think you are referring to *trenches*, or more specifically *submarine trenches*.  For example, the Mariana Trench is a submarine trench located in the Pacific Ocean, just east of the Mariana Islands.   \n\nAs you probably already know, it is the deepest part of the earth's oceans, and the deepest location of the earth itself.  It was created by ocean-to-ocean subduction, a phenomena in which a plate topped by oceanic crust is subducted beneath another plate topped by oceanic crust.\n\nCounting the distance from the bottom of the trench to the top of Mt. Lam Lam on the neighboring island of Guam would make Mt. Lam Lam taller than Mt. Everest.  Inhabitants of Guam like to call Mt. Lam Lam the tallest mountain in the world (tongue in cheek, of course).

Salton Sea.  It's in either Riverside or San Diego County.

I think its a port in Norway

10,916 meters (35,814 feet), to Challenger Deep in the Marianas trench, which is the deepest known part of the Earth's oceans.  The Marianas trench is in the western north Pacific Ocean.  \n\nSee sources.

Duh! trenches that are nowhere near the shoreline

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.
