At which location would a deep ocean trench be located?

At which location would a deep ocean trench be located?

western Pacific Ocean
The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth.

Which zone is only found at deep ocean trenches?

With depths exceeding 6,000 meters (nearly 20,000 feet), trenches make up the world’s “hadal zone,” named for Hades, the Greek god of the underworld, and account for the deepest 45 percent of the global ocean. The deepest parts of a trench, however, represent only about 1 percent or less of its total area.

Why are ocean trenches important?

They also are the deepest parts of the ocean floor. Trenches define one of the most important natural boundaries on the Earth’s solid surface, that between two lithospheric plates. A trench marks the position at which the flexed, subducting slab begins to descend beneath another lithospheric slab.

How many people have been to the Mariana Trench?

While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.

Where are most active seamounts found on the seafloor?

North Pacific Ocean
Seamounts and guyots are most abundant in the North Pacific Ocean, and follow a distinctive evolutionary pattern of eruption, build-up, subsidence and erosion. In recent years, several active seamounts have been observed, for example Loihi in the Hawaiian Islands.

How many seamounts are in the Pacific?

10,000 seamounts
There are more than 10,000 seamounts in the Pacific Ocean.

What lives in the trench zone?

What Animals Are in “the Trenches” or Hadalpelagic Zone?

• Giant Tubeworms. The scientific name for the giant tube worm is Riftia pachyptila.
• Starfish.
• Foraminifera (Forams)
• Cusk-eels.

What is the trench zone?

Understanding Ocean Zones: The Trench Zone Nearly three times deeper than the average depth of the sea floor, these zones are known as deep sea trenches. The trench zones are characterized by complete darkness and unimaginable pressures of up to 16,000 pounds per square inch.

What forms deep sea trenches?

In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
