What is another name for subduction zones?
Convergent plate boundariesDestructive plate boundaries
What takes place when one plate is forced down into the mantle beneath another plate?
When one plate is forced down into the mantle beneath another plate, it leads to a process known as subduction. This causes the descending plate to melt and generate magma, which can lead to volcanic eruptions and the formation of mountain ranges. Subduction zones are also associated with earthquakes due to the movement and interaction of the tectonic plates.
What does the phrase 'the less buoyant plate is subducted' mean?
This means that the cooler, heavier oceanic plate at an oceanic to oceanic convergent boundary is forced into the mantle - under the hotter, lighter oceanic plate. OR At oceanic to continental boundary the heavier oceanic plate is forced into the mantle under the lighter continental plate.
What is the process called when the oceanic plates slide down the slope of lithosphere-asthenospher boundary?
The process is called "subduction." It occurs when one tectonic plate moves beneath another at a convergent boundary, where the oceanic plate is forced down into the mantle at a subduction zone. This process leads to the recycling of old oceanic crust back into the mantle.
What feature marks the location where one tectonic plate is pushed underneath another plate?
The feature that marks the location where one tectonic plate is pushed underneath another plate is called a subduction zone. In these zones, the denser oceanic plate is typically forced down into the mantle beneath a lighter continental plate or another oceanic plate. This process can lead to the formation of deep ocean trenches and is often associated with volcanic activity and earthquakes.

What is the name of the process where ocean crust sinks back toward the mantle?
It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.
When does a part of oceanic plate sink into the mantle?
Usually when it meets another tectonic plate at a convergent plate boundary. If the oceanic plate converges with a continental plate the denser oceanic plate will be forced under the continental plate. If it converges with another oceanic plate the older (and therefore cooler and denser) plate will be forced under the younger plate.
What are formed where an oceanic plate is forced underneath another plate?
Subduction zones are formed where an oceanic plate is forced beneath another plate, typically a continental plate. This process typically leads to the formation of deep oceanic trenches, volcanic arcs, and seismic activity due to the subduction of the oceanic plate into the mantle.

Where is the oceanic crust sinking into mantle?
Usually when it meets another tectonic plate at a convergent plate boundary. If the oceanic plate converges with a continental plate the denser oceanic plate will be forced under the continental plate. If it converges with another oceanic plate the older (and therefore cooler and denser) plate will be forced under the younger plate.
What is the process of thrusting oceanic lithosphere into the mantle along a convergent plate boundary called?
The process of thrusting oceanic lithosphere into the mantle along a convergent plate boundary is called subduction. This occurs when one tectonic plate is forced below another due to their collision, leading to the recycling of Earth's crust and the formation of volcanic arcs.
What is the area called when one plate is forced under another plate?
The area is called a subduction zone, where one tectonic plate is being forced beneath another plate. This process can lead to the formation of deep ocean trenches and volcanic activity.
What is the plate boundary where oceanic crust is destroyed?
The plate boundary where oceanic crust is destroyed is a subduction zone. In this process, one tectonic plate is forced beneath another into the Earth's mantle. As the descending plate moves deeper into the mantle, it is eventually melted down and destroyed.
What is the process called when the oceanic plates slide down the slope of lithosphere-asthenospher boundary?
The process is called "subduction." It occurs when one tectonic plate moves beneath another at a convergent boundary, where the oceanic plate is forced down into the mantle at a subduction zone. This process leads to the recycling of old oceanic crust back into the mantle.
Which of these is a zone in which one plate is pushed down into the mantle underneath another plate?
This is known as a subduction zone. It is where one tectonic plate is forced beneath another due to tectonic forces, resulting in the recycling of crustal material back into the mantle. These zones are often associated with deep ocean trenches and volcanic arcs.
