Transcript of Mariana Trench
Cameron arrived at the bottom with the technology to collect scientific data, unthinkable in 1960
When the only other manned Challenger Deep dive took place James Cameron “I felt like I — in the space of one day — had gone to another planet and come back,” he said, saying the ocean floor was a “completely featureless, alien world.” -James Cameron The Mariana Trench is the deepest part of all the worlds oceans. The formation of the Mariana Trench was by the subduction of the Pacific Plate
as it was forced to slide under the smaller Mariana Plate at the bottom of the ocean between Japan and New Guinea
which resulted in tensions and faults in the earth's crust Ocean trenches represent the deepest parts of the ocean floor
The deepest being the Mariana Trench which has a depth of 11,034 m/36,201 ft.
At depths of below 6 km/3.6 mi there is no light and very high pressure A trench is formed where the oceanic plate dives below (is subducted by) the (less dense) overriding plate. The Pacific is the world's largest ocean. Its area is greater than all of the world's dry land
The average depth of the Pacific is just over 4,000m and it contains the deepest ocean trenches in the world. The Mindanao trench, close to the Philippines, is six and a half miles deep and the lowest point is the Marianas Trench. At least 22 trenches have been identified
although not all are classified as major.
Of this number, 18 are in the Pacific Ocean, three in the Atlantic Ocean, and one in the Indian Ocean. Oceanic trenches (Mariana Trench) A deep-sea trench is a narrow, v-shaped hole in the ocean floor
Trenches are the deepest parts of the ocean and the lowest points on Earth
reaching depths of nearly 7 miles (10 km) below sea level
These holes can be thousands of miles in length, yet as little as 5 mi (8 km) in width Where are ocean trenches usually located? While the Japan trench is 29,500 ft at it's deepest, surprisingly the Mariana Trench is 36,070 ft deep! Ocean trenches are found around the edge of the Pacific Ocean and the northeastern Indian Ocean
minor ones occur in the Caribbean and near the Falkland Islands Their locations are very close to each other The Mariana Trench is located just east
of the 14 Mariana Islands near Japan.
