Where are the trenches located in the world?
There are about 50,000 kilometers (31,000 mi) of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level.
How many trenches are there in the world?
Trenches are relatively narrow, usually less than 100 km (about 60 miles) wide. Of the Earth’s 20 major trenches, 17 are found in the Pacific basin, a vast area rimmed by trenches of both marginal and island arc varieties.

Where are the deepest trenches found?

Main difference between the two trenches was that the Germans dug their trenches first, which meant they got the better soil conditions because they dug their trenches on higher ground compared to the British trenches.
Which ocean is deepest?
western Pacific Ocean
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
What is under Mariana Trench?
The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. “These are some of the deepest holothurians ever observed, and they were relatively abundant,” Gallo said.
What is the second deepest trench in the world?
Tonga Trench
Tonga Trench
The deepest point in the Tonga trench, known as the Horizon Deep, is considered the second deepest point on Earth after the Challenger Deep and the deepest trench in the Southern Hemisphere.

How deep has a human gone in the ocean?
35,853 feet
Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
How deep is the deepest part of the world?
Toward the southern end of the Mariana Trench lies the Challenger Deep. It sits 36,070 feet below sea level, making it the point most distant from the water’s surface and the deepest part of the Trench.
Which ocean is coldest?
The Arctic Ocean
The Arctic Ocean | National Geographic Society.
Why is the Mariana Trench so deep?
One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.
Does anything live in the Mariana Trench?
The Mariana Trench is deeper than Mount Everest is tall and anything living there has to survive the cold water and extremely high pressure. Some animals, including the deep-sea crustaceans Hirondellea gigas , do live there —and they have recently had a human visitor.
Where is the second deepest place on Earth?
Tonga Trench
Tonga Trench: 35,702 ft Deep
The second deepest place on Earth is the Tonga Trench, located in the south-west Pacific Ocean.
Have we reached the bottom of the ocean?
2012: Filmmaker James Cameron, of Titanic and Avatar fame, completed the first solo mission to the bottom of the Challenger Deep in his vessel the Deepsea Challenger. 2019: Victor Vescovo reached a deeper part of Challenger Deep at 35,853 feet, breaking the record for the deepest dive in DSV Limiting Factor.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
What did the trenches smell like?
The stink of war
Then there was the smell. Stinking mud mingled with rotting corpses, lingering gas, open latrines, wet clothes and unwashed bodies to produce an overpowering stench. The main latrines were located behind the lines, but front-line soldiers had to dig small waste pits in their own trenches.
Do any trenches still exist?
A few of these places are private or public sites with original or reconstructed trenches preserved as a museum or memorial. Nevertheless, there are still remains of trenches to be found in remote parts of the battlefields such as the woods of the Argonne, Verdun and the mountains of the Vosges.
