What is the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary called?
The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary is called subduction. This occurs because oceanic crust is denser than the underlying asthenosphere, causing it to be pulled down into the mantle. Subduction zones are associated with the formation of volcanic arcs and deep-sea trenches.
What plate boundary does a deep ocean trench form on?
A deep ocean trench typically forms at a subduction zone, which is a convergent plate boundary where one tectonic plate is forced beneath another into the mantle. This process results in the formation of deep trenches in the ocean floor, such as the Mariana Trench in the western Pacific Ocean.
What s created when one plate moves under another a mantle or a trench?
When one tectonic plate moves under another, a trench is created. This process, known as subduction, occurs at convergent plate boundaries where an oceanic plate is forced beneath a continental or another oceanic plate. The subduction zone forms a deep oceanic trench, which is often associated with geological activity such as earthquakes and volcanic eruptions. The mantle beneath the plates may also be affected, but the direct result of this interaction at the surface is the formation of a trench.
How do the plates touching the mariana trench move?
The Mariana Trench is formed by the subduction of the Pacific Plate beneath the Mariana Plate. As these tectonic plates interact, the denser Pacific Plate is forced down into the mantle, creating a deep trench. This movement is driven by the process of plate tectonics, where convection currents in the Earth's mantle cause the plates to shift. The interaction can also lead to seismic activity, including earthquakes, as the plates grind against each other.
What is subuction?
Subduction is the process where one tectonic plate moves beneath another plate into the Earth's mantle at a convergent boundary. This can lead to the formation of deep ocean trenches and volcanic activity. It is a fundamental process in plate tectonics that drives the movement and interaction of Earth's lithospheric plates.
What would happen to the process of the sea floor spreading if the heat from the core no longer existed?
A deep trench to the mantle

What is the process shown occurring at deep ocean trench?
The process shown occurring at a deep ocean trench is subduction, where one tectonic plate is being forced beneath another into the Earth's mantle. This process is a key element of plate tectonics and is responsible for creating deep ocean trenches and volcanic activity.
The place where the ocean floor suddenly plunges downward is?
The place where the ocean floor suddenly plunges downward is called a submarine trench. These deep underwater valleys form at tectonic plate boundaries where one plate is being pushed beneath another in a process known as subduction. Submarine trenches can reach depths of over 10 kilometers and are some of the deepest parts of the ocean.

How and why does an oceanic trench form?
The earth has plates and when the earth shirfts its plates it open a trench canyon like structure. sorry if my grammer is not perfect. An oceanic trench forms when a denser plate is subducted into the Earth at a convergent plate margin. Because the denser plate (always oceanic crust) is being bent and pulled down into the mantle, a trench forms at this subduction zone.
What is the process of the ocean floor sinking beneath a deep ocean trench and back into the mantle known as?
The process of the ocean floor sinking beneath a deep ocean trench and back into the mantle is known as subduction. This occurs at convergent plate boundaries where one tectonic plate is forced beneath another due to differences in density. Subduction zones are associated with volcanic activity and the formation of mountain ranges.
SUbduction occurs where the oceanic crust bends down toward the mantle at a(an)?
deep ocean trench.
What is subuction?
Subduction is the process where one tectonic plate moves beneath another plate into the Earth's mantle at a convergent boundary. This can lead to the formation of deep ocean trenches and volcanic activity. It is a fundamental process in plate tectonics that drives the movement and interaction of Earth's lithospheric plates.
Which direction does the Benioff Zone descend from the trench into the mantle?
The Benioff Zone is formed when a piece of oceanic crust is being subducted into the mantle. This line of earthquakes follow the angle of the subducting plate as it slides beneath the continental crust.
A deep valley along the ocen floor beneath which oceanic crust slowly sinks toward mantle?
That feature is known as a deep-sea trench, where one tectonic plate is subducted beneath another. The process creates deep oceanic trenches, such as the Mariana Trench, which is the deepest point on Earth's surface.
