When a tectonic plate is forced into the mantle, this process is known as subduction. It occurs at convergent boundaries where one plate, typically an oceanic plate, is denser and sinks beneath another plate, which can be either continental or another oceanic plate. This process leads to geological phenomena such as the formation of deep ocean trenches, volcanic arcs, and earthquake activity due to the release of stress as the plates interact. Subduction plays a crucial role in the recycling of Earth's crust and the dynamic nature of plate tectonics.

What is it called when 1 plate is forced under another in to the mantle?
Subduction is the process where one tectonic plate is forced below another plate into the mantle. This can lead to the formation of deep ocean trenches and volcanic activity.
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 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.

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.

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.
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.

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.
Which process or processes are involved in the sinking of cold ocean plates into the mantle?
The process involved in the sinking of cold oceanic plates into the mantle is called subduction. This occurs at convergent plate boundaries where the denser oceanic plate is forced beneath the less dense continental plate. As the oceanic plate sinks into the mantle, it undergoes partial melting, causing volcanic activity along the subduction zone.
In which area does an oceanic plate subduct into the mantle?
An oceanic plate subducts into the mantle at convergent plate boundaries.
How was the Challenger Deep formed?
The challenger deep was formed when the Philippine plate and the pacific plate had a collision forced the heavier pacific plate down toward the mantle, and the edge of the Philippine plate was dragged down creating a steep walled trench.
