What Oceanic feature found at subduction zones are the deepest parts of the ocean?
trenches
The deepest parts of the ocean are found in trenches—at more than 35,000 feet (nearly 11,000 meters), Challenger Deep is a part of the Mariana Trench, where the Pacific Plate is subducting beneath the Philippine Plate.
Where would there be a deep ocean trench indicating a subduction zone?
Trenches are located in subduction zones at or near a convergent boundary, continental crust, and/ or volcanic islands. The Mariana Trench is the deepest known trench globally, located more than 35,000 feet below sea level.
What are the depths of the ocean zones?
The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the …
What would you find at a subduction zone?
Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.) At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust.
Do we know the deepest part of the 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 36,200 feet deep.
Which is the deepest part of the ocean?
Its maximum depth has been measured at 11,034 m in the Challenger Deep, though some studies have reported it to be 10,910 m deep. It is interesting to note that Mt. Everest, the tallest peak on Earth is made to stand in the deepest part of the Mariana Trench would still be covered with more than a mile of water.
Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust.
Where are the trenches located in the ocean?
Ocean trenches are steep depressions in the deepest parts of the ocean [where old ocean crust from one tectonic plate is pushed beneath another plate, raising mountains, causing earthquakes, and forming volcanoes on the seafloor and on land.
Which is the second deepest trench in the southern hemisphere?
The Tonga Trench is known to be the second deepest natural trench on the earth. It is also the deepest natural trench in the Southern Hemisphere. It is located in the southwestern part of the Pacific Ocean at the Kermadec Tonga Subduction Zone’s northern end. The Kermadec Ridge is the region between the Lau back-arc basin and the Tonga Trench.
