Where is the deepest ocean trench in the world? How deep?

The Mariana Trench is located in the western part of the Pacific Ocean and is part of a series of trenches on the ocean floor in the western Pacific Ocean.

Divide. It is located between the Asian and Pacific plates, from the Iwo Islands in the north to the vicinity of Yap Island in the southwest. To the north there are Alauts, Kuril Islands, Japan, Ogasawara and other trenches, and to the south.

There are trenches such as New Britain and New Hebrides. The total length is 2,550 kilometers, arc-shaped, with an average width of 70 kilometers, and most of the water depth is more than 8,000 meters. The maximum water depth is 11,034 meters in the Charinger Abyss (the depth varies from year to year), which is the deepest point on Earth.

The deepest part of the Mariana Trench is called the Charinger Abyss, and its name is given in honor of the British ship Charinger 8, which discovered it. In 1951, Charlinger 8 detected a depth of 10,836 meters; In 1957, the Soviet ship Vityaz measured a depth of 11,034 meters using acoustic reflectors; In 1960, the American manned submersible "Trieste" successfully reached the bottom of the Charinger abyss, and the depth measured by a plumb hammer was 10,912 meters; In 1984, the Japanese ship Takuyo measured a depth of 10,924 meters; The depth measured by Japan's Trench submersible in March 1995 was metres.

The deepest conglomerate trench in the world is the Mariana Trench.

Further information is as follows:

1.The geographical location of the Mariana Trench

The Mariana Trench is a long, narrow trench trending north-east, northwest at a distance of about 250 kilometers in the northwestern Pacific Ocean. Its coordinates are 11°21 north latitude', longitude 142°12 E'。

2.The depth of the Mariana Trench

The deepest part of the Mariana Trench is known as the Challenger Deep, and its depth is about 10,916 meters (35,827 feet). This depth is deeper than the altitude of Mount Everest. The Challenger Abyss is one of the deepest earthly frontiers on the Earth's surface.

3.Causes of the formation of the Mariana Trench

The formation of the Mariana Trench is related to plate tectonics. This is where the Pacific and Philippine plates collide, and the difference in density between them caused the Pacific plate to subduct downward, creating this trench tens of thousands of meters deep.

4.Features of the Mariana Trench

The geological features of the Mariana Trench are remarkable. It is one of the oldest ocean trenches in the world, formed about 40 million years ago and has been around for tens of millions of years. The interior of the trench has great water pressure, low temperatures, darkness and lack of sunlight, and relatively few species of organisms.

5.Scientific research in the Mariana Trench

The Mariana Trench is of great value to scientists. It is the only place on Earth where the deep structure of the Earth's crust and the material of the Earth's mantle can be directly observed. Scientists have conducted in-depth studies of ocean trenches with exploration equipment and submersibles, revealing the mysteries of the Earth's interior.

6.Biological environment of the Mariana Trench

Despite the harsh environment of the Mariana Trench, there are still some organisms that have adapted to such an environment. Some special species of organisms survive in the trenches, such as red tide plankton on the shallow bottom, benthic animals, and fish that live mainly on the bottom of the sea.

7.Human exploration of the Mariana Trench

Human exploration of the Mariana Trench dates back to the 20s of the 20th century. The most famous expedition was in 1960, when American oceanographer Don Walsh and Swiss engineer Jacques Picka successfully descended to the Challenger Depths aboard the submarine Challenger, becoming the first humans to reach the deepest part of the trench.

8.Summary

The Mariana Trench is the deepest trench in the world, located in the Pacific Northwest, and its deepest point is called the Challenger Deep, which is about 10,916 meters deep. This trench is of great scientific value and is also a habitat for some special organisms. It has been explored many times to uncover the mysteries of the Earth's inner circle.

1. The deepest ocean trench in the world is at the bottom of the Pacific Ocean near the Mariana Islands in the northeastern part of the Philippines.

2. The Mariana Trench, also known as the Mariana Trench. It is located at 11°20 N, 142°, from Sulphur Puhuang Island in the north to Yap Island in the southwest. It has the Aleutian, Kuril Island, Ogasawara and other sea trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers and an arc shape, with an average width of 70 kilometers.

It is estimated that the trench has been formed for 60 million years.

3. The deepest part of the trench is 6 11 kilometers, which is the deepest known ocean, where the water pressure is high, the total darkness is low, the temperature is low, the oxygen content is low, and the food imitation chain resources are scarce, so it has become one of the most harsh areas on the earth.

4. The Mariana Trench is a plate subduction zone, and the geological movement of the seabed is very active, and the material composition and genesis of seamount volcanic rocks are of interest to marine geologists.

The deepest seabed is the Fichaz Abyss in the Mariana Trench, with a maximum depth of 11,034 meters.

The Mariana Trench is formed by the subduction of the Pacific Plate below the Philippine Plate, and the entire subduction system is about 2,800 kilometers long, trending north-south, and most of the water depth of the trench is more than 8,000 meters. If the world's highest mountain, Mount Everest, is placed at the bottom of the ditch, the summit will not be able to expose the water. Many mountaineers have successfully conquered Mount Everest, but it is extremely difficult to explore the deep sea.

At its deepest point of 6,11 kilometres, the Mariana Trench is the deepest known ocean and is one of the harshest areas on Earth due to its high water pressure, total darkness, low temperatures, low oxygen levels and lack of food resources.

The deepest is the Mariana Trench, which is the deepest point on Earth at 11,034 meters.

1. The Mariana Trench, also known as the "Mariana Islands Trench", is the deepest trench on the earth, which is located in the western North Pacific Ocean seabed, near the east of the Mariana Islands. The Mariana Trench is already deeper below sea level than the highest point of Mount Everest.

2. The Mariana Trench is located at 11

20 n, 142°, that is, in the northeast of the Philippines, the Pacific Ocean floor near the Mariana Islands, between the Asian continent and Australia, from the Iwo Islands in the north to the vicinity of Yap Island in the southwest. It has the Aleutian, Kurile, Japan, Ogasawara and other trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers, an arc, an average width of 70 kilometers, and most of the water depth is more than 8,000 meters. The deepest point is in the Fichaz Abyss, at 11,095 meters, which is the deepest point on Earth.

The trench is estimated to have formed 60 million years ago and is part of a series of trenches on the ocean floor in the western Pacific Ocean.

3. Causes.

The Mariana Trench, located east of the Mariana Islands in the western North Pacific Ocean, is an arc-shaped depression with an ocean floor extending for 2,550 kilometers and an average width of 69 kilometers. There are smaller steep-walled valleys at the bottom of the main trench. In 1957, the Soviet survey ship measured a depth of 10,990 meters, and later a new record of 11,929 meters was set again.

In 1960, the U.S. Navy used the French-made "Trieste" deep-sea submersible to set a record of 10,911 meters in the trench. It is generally believed that the oceanic plate and the continental plate collide with each other, and because the oceanic plate rocks are dense and low, they subduct under the continental plate, enter the mantle and gradually melt and disappear. Ocean trenches are formed where collisions occur, and island arcs and coastal mountains are often formed on the side close to the mainland.

These places are all areas of intense geological activity, manifested by volcanic eruptions and **.

Mariana Trench (Mariana Trench, also known as Mariana Trench). It is located at 11°20 N, 142°, that is, the Pacific Ocean floor near the Mariana Islands in the northeast of the Philippines, from Iwo Jima in the north to Yap Island in the southwest. It has the Aleutian, Kuril Island, Ogasawara and other trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers, an arc, and an average width of 70 kilometers.

It is estimated that the trench has been formed for 60 million years. At its deepest point of 6,11 kilometres, the Mariana Trench is the deepest known ocean and is one of the harshest areas on Earth due to its high water pressure, total darkness, low temperatures, low oxygen levels and lack of food resources.

the world's deepest trench, the Mariana Trench; At 11°20 N, 142°, i.e. the northeastern part of the Philippines, near the Mariana Islands, at the bottom of the Pacific Ocean, from Iwo Jima in the north to Yap in the southwest.

Mariana Trench (Mariana Trench, also known as Mariana Trench). There are Aleutian, Kuril Island, Ogasawara and other trenches in the north, and New Britain and New Hebrides in the south. Its deepest point is usually 6-11 kilometers, and the deepest point reaches 11,034 meters, even if the entire Mount Everest is still left in it, there have been many scientific expeditions that have tried to conduct scientific research there, but the mystery found so far is relatively limited.

Seabed mineral deposits in the Mariana Trench

In January 2011, an international team of scientists discovered that the Mariana Trench contains large amounts of carbon, meaning that the trench's role in regulating the Earth's environment is more important than previously thought. The Mariana Trench acts as a sediment collector, and the amount of carbon converted by bacteria in the trench is higher than that on the 6,000-meter-deep submarine plain.

This suggests that the carbon content in the trench is higher than the researchers previously thought, and they were unaware that there is such a carbon dioxide collection tank in the deep sea. The next step for scientists is to quantify the results of their research, figuring out how much more carbon is in the deep-sea trench than in other oceans, and how much carbon is converted by bacteria, which could help scientists better understand the role of the deep-sea trench in regulating the climate.
