The Deepest Ocean Floor

The trench is 1 554 miles long and 44 miles wide or 120 times larger than the grand canyon.
The deepest ocean floor. Finally you would ascend tens of thousands of feet back up the continental slope and across the continental shelf. It is the deepest oceanic trench on earth. In 1960 the bathyscaphe trieste descended to the bottom of the mariana trench near guam at 10 911 m 35 797 ft. In 2010 the united states center for coastal ocean mapping measured the depth of the challenger deep at 10 994 meters 36 070 feet below sea level with an estimated vertical accuracy of 40 meters.
If mount everest 8 848 metres were submerged there its peak would be more than a mile beneath the surface. According to the national oceanic and atmospheric administration the trench is almost 5 times wider than it is deep. The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres east of the mariana islands. 6 780 mi the deepest known spot in any ocean.
The challenger deep is the deepest spot in the ocean floor. Measuring the greatest ocean depth the challenger deep in the mariana trench is the deepest known point in earth s oceans. Oceanic trenches in the ocean are long but narrow topographic depressions on the sea floor the deepest parts of the ocean floor. Noaa the deepest part of our oceans the region from below 20 000 feet to the very bottom of the deepest sea trench is known as the hadal zone.
The oceans deepest area is the mariana trench also called the marianas trench which is in the western part of the pacific ocean. However some unrepeated measurements place the deepest portion at 11 034 metres. At its deepest part it s just under 7 miles 6 831 miles. It reaches between 35 755 and 36 197 feet below the nearby surface of the seabed depending on how it is measured either by sonar bathymetry or submersibles.
Ocean trenches after scaling the mid ocean ridge and traversing hundreds to thousands of miles of abyssal plains you might encounter an ocean trench. The maximum known depth is 10 984 metres at the southern end of a small slot shaped valley in its floor known as the challenger deep. It is crescent shaped and measures about 2 550 km in length and 69 km in width. The pacific ocean has around 50 000km of convergent plate margins and most of the deepest point located around this place.
It s named after hades the underworld of greek.
