The deepest part of the ocean floor is several kilometers above sea level

The Mariana Trench is the deepest trench in the world.

The maximum water depth is in the Fichaz Abyss, which is 11,034 meters, which is the deepest point on Earth.

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.

Seafloor Expansion:

It was not until the 50s of the 20th century that geographers were able to map the underwater world with advanced technology. The results of the surveying and mapping show that there is a rather towering ocean "ridge" on the bottom of the sea, forming an underwater "mountain range", which stretches for about a kilometer and passes through all the world's oceans, and the "ridge" at the bottom of the ocean is also called the fault valley.

Rock mama is constantly emerging from the fault valleys, and when the magma cools, it creates a series of new submarine seamounts that rise and fall at the bottom of the ocean, a process called seafloor expansion, and these new seamounts are called sea ridges. As new rocks are added to the fault valley, the rocks on both sides of the fault valley gradually move away from the ocean ridge**. So, the farther away from the "mountains" the rocks are, the older they are.

The world's deepest seabed is the Mariana Trench, which has a maximum depth of 11,034 meters below sea level, but measurements vary from country to country.

The Mariana Trench is located on the western seabed of the Pacific Ocean, near the eastern part of the Mariana Islands. The trench is located in the convergence subduction zone of the two plates, where the Pacific plate subducts below the Philippine plate. The Mariana Trench is much deeper below sea level than the elevation of Mount Everest.

Since the 50s of the 20th century, the Mariana Trench has been explored several times by countries around the world. The trench was discovered in 1951 by the British ship Charlinger 8, which was detected at a depth of 10,836 meters, and this data has been continuously updated since then. In 1957, the Soviet survey ship measured the depth of the trench as 10,990 meters, and soon after another scientist measured the depth of 11,929 meters.

On January 14, 1960, Swiss physicist Jacques Piccard and U.S. Navy personnel Walsh, known as the bathyscaphe "Trieste", dived to the bottom of the Mariana Trench to a depth of 10,916 meters for scientific investigation, which was the first time that mankind ever reached the deepest part of the seabed. However, due to the pressure on the seabed, a slight crack appeared in a 19-centimeter-thick porthole of the "Trieste", and Piccard had to rush to the surface after 20 minutes at the bottom of the sea.

In 1992, Japan's Marine Science and Technology Center spent $50 million to develop the "Trench" underwater robot, which is a cable-controlled underwater robot. After several failures, on March 24, 1995, the Trench was lowered to the bottom of the sea by a 12,000-metre-long cable, and after a three-and-a-half-hour journey, the Trench reached the bottom of the sea, correcting the depth to one metre.

On April 23, 2020, the deep-sea submersible Haidou-1 developed by China went to the Mariana Trench aboard the "Exploration 1" scientific research vessel, and successfully completed four 10,000-meter sea trials and experimental application tasks, with a maximum depth of 10,907 meters.

The depth of the seabed is as high as 11,034 meters, and everyone doesn't know much about the ocean. With the continuous development of science and technology, the mysteries of the ocean are constantly being explored. The deepest part of our planet is the Mariana Trench, which is located between the northeastern Philippines, the Pacific Ocean near the Mariana Islands, the Asian continent, and Australia.

On this trench, it is the deepest part of the Fichaz Abyss, at 11,034 meters deep, which is said to be the deepest part of the Earth. The trench is 2,550 meters long, 70 kilometers wide on average, and has an average depth of more than 8,000 meters. This trench has been formed for about 60 million years and is part of the western Pacific Trench.

The Mariana Trench is located at latitude 11 °20 N, longitude 142 °E; , that is, the bottom of the Pacific Ocean near the Mariana Islands in the northeastern part of the Philippines. The deepest point was 11,034 meters in the past, and some sources now put it at 11,929 meters.

The Maria Trench is located at latitude 11 °20 N, longitude 142 °E; , that is, in the northeast of the Philippines, the Mariana group of dao islands.

Near the bottom of the Pacific Ocean.

The deepest place in the right used to be 11,034 meters, and now there are some materials that are 11,929 meters, and I have heard that the United States has been to a place of 20,000 meters.

As of August 1, 2020, the Mariana Trench is the deepest known ocean, with a maximum depth of 6,11 km.

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

How deep is the deepest part of the ocean floor? I seem to have heard of this, and there is almost the deepest one. Four.

Fifty kilometers away. That's 50 kilometers at a depth. 1 km is 1 km, and the depth is 50 km.

What is the concept? Really think about it. I find it difficult to explore the bottom of the sea.

Maybe 20,000 miles, didn't Verne write a book called 20,000 Leagues Under the Sea?

Located in the western North Pacific Ocean seabed, the Mariana Trench to the east of the Mariana Islands is the deepest known trench, with most of the water depth above 8,000 meters. The deepest point is in the Fichaz Abyss, at 10,924 meters, which is the deepest point on Earth.

The deepest part of the seabed, which is unimaginable, is currently several kilometers.

Now the places that humans can detect are more than 18,000 meters at most, and there are deep sea hells, and now humans have not explored how deep the bottom of the sea is?

The Mariana Trench, located east of the Mariana Islands in the western North Pacific Ocean, is an arc-shaped depression on the ocean floor that extends for 2,550 kilometers and is 69 kilometers wide on average. 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 11,034 meters was set later.

Made in France by the US Navy in 1960""of Trieste""The exploration boat 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 dissolve and die. 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, which manifest themselves as volcanoes and **.

The maximum length of the Pacific Ocean is about 15,900 kilometers from north to south, and the maximum width from east to west is about 109,900 kilometers. The total area is 178.68 million square kilometers, accounting for one-third of the earth's surface area and one-half of the world's ocean area. The average depth is 3,957 meters, and the maximum depth is 11,034 meters.

I've never been to the deepest part of the sea, I'm afraid I'll drown.

I don't know about this yet, but I read a children's book called "20,000 Leagues Under the Sea".

The Mariana Trench is the deepest trench in the world, and it is located in the northeastern part of the Philippines

The Pacific Ocean floor near the Mariana Islands is centered at 15°N latitude and 147°30 E longitude.

Its maximum depth reaches 11,034 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.

There should be 10,000 meters. There should be deeper, but I haven't found it yet.

You can go and see the Guinness Book of Records, the deepest distance to the sea.
