Describe the Process of Subduction at a Deep Ocean Trench

Which type of zone is located at a deep-ocean trench. Trenches are formed by subduction a geophysical process in which two or more of Earths tectonic plates converge and the older denser plate is pushed beneath the lighter plate and deep into the mantle causing the seafloor and outermost crust the lithosphere to bend and form a steep V-shaped depression.

As the sinking plate moves deeper into the mantle fluids are released from the rock causing the overlying mantle to partially melt.

. Convergent divergent subduction transform 2 See answers. The material of the plates is renewed by a process of being forced into the Magma usually causing a deep trench in the Ocean floor called subduction zones and by bubbling up of material from the Magma in upwelling zones. Diffusion is a very slow process.

As the subducting slab moves under the less dense plate some of. The plate that is slipping under. At some points the oceanic crust bends downward and forms a deep-ocean trench.

Also located in mid Ocean submerged mountain ranges like the mid Atlantic ridge where the upwelling is making the ocean broader. As the ocean a ges subduction. The trench is 1585 miles long and 428 miles wide and is formed when the Pacific Plate subducted beneath the Philippine Sea Plate.

1 What is the process shown occurring at B. Deep ocean trenches are formed during a process known as subduction. A strong answer will describe the topography and bathymetry specifically width and depth of the Izu-Bonin Trench at the target location and compare these characteristics with other portions of the trench noting and quantifying where possible differences in its width and depth associated with the intersection of the chain of Pacific seamounts.

Ocean trenches are driven by. This type of tectonic is happening in several places around the world such as. First of all subduction causes deep ocean trenches.

3 What process is shown occurring at ocean floor and why does it occur. The Ryukyu Trench stretching out from southern Japan is formed as the oceanic crust. A region where this process occurs is known as a subduction.

The point at which this happens is called the subduction zone. The process of opening and closing of the ocean basins is called as Supercontinent. Describe the process of subduction.

Why does subduction. Then the oceanic crust sinks back into the mantle through a process called subduction. The process by which the Earths crust is destroyed is called subduction and it most commonly occurs at the deep ocean regions of the world where ocean trenches are formed.

Log in for more information. Subduction allows part of the ocean floor to sink back into the mantle over tens of millions of years. The lava spreads out pushing older rocks aside.

Usually one of the converging plates will move beneath the other a process known as subduction. 4 What process results in the ocean floor sinking beneath a deep-ocean trench and back into the mantle. In subduction one tectonic plate a large portion of the Earths crust slides under another.

Get an answer. Subduction is a geological process in which the oceanic lithosphere is recycled into the Earths mantle at convergent boundaries. The Process of Subduction The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle is called subduction.

5 What happens to the old oceanic crust. Whats an ocean trench. The subduction zones and the activities resulting from it are the cause of formation of oceanic trenches.

The process by which the ocean floor sinks beneath continental crust at a deep-ocean trench and back into the mantle is known as Subduction Describe the process of sea-floor spreading Molten material rises from the mantle and erupts through the mid-ocean ridge. As subduction occurs the crust closer to a mid-ocean ridge moves away from the ridge and toward a deep-ocean trench Advertisement Survey. 6 What is the name of the geological.

Some of the most familiar ocean trenches are the result of this type of convergent plate boundaryThe Peru-Chile Trench off the west coast of South America is formed by the oceanic crust of the Nazca plate subducting beneath the continental crust of the South American plate. When the oceanic plate is forced below the continental plate it melts to form magma and earthquakes are triggered. This makes it very dense.

As subduction occurs the oceanic crust moves from the toward a. Most scientists however describe subduction as a rough scraping activity that is characterized by high amounts of friction as the two plates rub past each other. The Process of Subduction Explanation.

The deep earthquakes below subduction zones occur in a plane that dips 30 or more under the overriding plate. The most explosive volcanoes erupt in the subduction zone. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.

Why is active transport necessary for cells. The movement of the Earths crust at the convergent boundaries of tectonic plates be it oceanic crust and continental crust or two oceanic crusts result in a steep deep valley with the two crusts acting as its walls. As subduction occurs the oceanic crust moves from ridge and toward a deep-ocean trench.

In subduction one tectonic plate moves under another. Describe the process of subduction at a deep-ocean trench. Describe how a deep ocean trench is formed.

2 What process is shown occurring at C and why does it occur. Deep Sea Trenches are distributed in. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate the heavier plate dives beneath the second plate and sinks into the mantle.

Both types of subduction zones are associated with large earthquakes that originate at a depth of as much as 700 km 435 miles. Ocean trenches are long steep-sided depressions on the ocean floor extending for thousands of miles in length and as little as a few miles across. Search for an answer or ask Weegy.

Subduction happens when two convergent boundries come together and 1 slides under the other causing a deep ocean trench. - 25677301 jordansoccer46 jordansoccer46 11222021 Biology High School answered Which type of zone is located at a deep-ocean trench. The reason that the Mariana Trench is so deep is that the crust at the edge of the Pacific plate is one of the oldest portions of oceanic crust in the world.

Trenches are formed by subduction a geophysical process in which two or more of Earths tectonic plates converge and the older denser plate is pushed beneath the lighter plate and deep into the mantle causing the seafloor and outermost crust the lithosphere to bend and form a steep V-shaped depression.
