8428 meters below sea level. I dont know feet
The Southern Ocean is the fourth largest ocean in the world at 20,327,000 sq km. Its deepest point is the South Sandwich Trench at 7,235 metres.
The Hellenic trench is about 5000 meters or 16404 feet at the Matapan Deep system.
35,400 feet deep
First off, its Mariana Trench, and it is at 11,033 meters (36,201 feet) deep
A couple Billion feet
Challenger Deep is a very deep spot on Mariana's Trench. Mariana's Trench is very long and Challenger Deep is just a tiny part of it, considered the deepest part.
in excess of 400 feet
The deepest trenches in the world are -1 - Mariana Trench (aka Challenger Deep) in the western Pacific Ocean at 11,034 metres deep.2 - Tonga Trench in the south Pacific Ocean at 10,882 metres deep.3 - Philippine Trench (aka Philippine Deep, Mindanao Trench and Mindanao Deep) in the western Pacific Ocean at 10,540 metres deep.
The deepest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench at a depth of 10,911 m (35,798 ft) below sea level.Underwater the Marianas Trench would be the deepest Trench in the World.Challenger Deep's Deepest part is about 35,838 feet deep (11035 meters).The deepest point in any ocean is the Mariana Trench (aka Challenger Deep) in the western Pacific Ocean at 11,033 metres deep.
Yes. Not sure if "trench" is the exact scientific term, but there is certainly a canyon, or trench there. Around 3000 feet deep.
Yes, it is. The deepest points in theoceans of the Earth are in order:Deepest Point in the World (and Pacific Ocean)Challenger Deep, Mariana Trench, Western Pacific Ocean: 35,840 feet / 10,924 metersDeepest Point in the Atlantic OceanPuerto Rico Trench: 28,374 feet / 8648 metersDeepest Point in the Arctic OceanEurasia Basin: 17,881 feet / 5450 metersDeepest Point in the Indian OceanJava Trench: 23,376 feet / 7125 metersDeepest Point in the Southern OceanSouthern end of the South Sandwich Trench: 23,736 feet / 7235 metersNO it is not the Puerto Rico Trench.The 2nd deepest deep ocean trench in the world is the Philippine Trench, its deepest part is called the Galathea Depth: 10,540 meters (5,763 fathoms or 34,580 feet).Actually, the 2nd deepest TRENCH is the Tonga Trench, with a maximum depth of 10880 m in the Horizon Deep. The 1st, 2nd and 3rd deepest deeps are located in the Mariana Trench. Challenger Deep, 10912 m; Vitiaz Deep, 10908m; and Serena deep, ~10890 m. An interesting point is that only the Challenger and Vitiaz deeps have been confirmed by dives to the bottom. All the other deeps have only been measured by sonar, which can easily have over 100 m of error, often on the side of over-estimation. Until a dive to the Vitiaz deep in 2009 by the ROV Nereus, the official (Sonar) depth was 11022 m.You're Both wrong:TrenchOceanDepthMariana TrenchPacific Ocean11,033mTonga TrenchPacific Ocean10,882mKuril-Kamchatka TrenchPacific Ocean10,542 mPhilippine TrenchPacific Ocean10,540 mKermadec TrenchPacific Ocean10,047 mIzu-Bonin Trench (Izu-Ogasawara Trench)Pacific Ocean9,780 mJapan TrenchPacific Ocean9,000 mPuerto Rico TrenchAtlantic Ocean8,605 mPeru-Chile Trench or Atacama TrenchPacific Ocean8,065 m
The deepest part of the Indian ocean is in the Diamantina Trench. It is 26,401 feet and 8,047 meters deep.
