At an oceanic-oceanic convergent boundary, one tectonic plate is forced beneath another in a process called subduction. This occurs when two oceanic plates collide, with the denser plate descending into the mantle, creating a deep ocean trench. As the subducting plate melts, it can lead to volcanic activity, forming island arcs. This dynamic interaction also contributes to seismic activity in the region.

What type of boundary forms when an oceanic plate is pushed under a continental plate?
A convergent boundary forms when an oceanic plate is pushed under a continental plate. This process, known as subduction, can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
What happens when oceanic and continental plates collide?
When oceanic and continental plates collide, the oceanic plate is usually forced under the continental plate in a process called subduction. This can result in the formation of mountain ranges on the continental plate and can lead to the creation of volcanic arcs. The collision can also cause earthquakes and tsunamis.
What happens at an oceanic oceanic convergent plate boundary?
At an oceanic-oceanic convergent plate boundary, two oceanic tectonic plates collide, leading to the subduction of one plate beneath the other. This process creates a deep ocean trench and can result in volcanic activity as the subducted plate melts and forms magma. Over time, this can lead to the formation of volcanic island arcs, such as the Aleutian Islands in Alaska. Earthquakes are also common in these regions due to the intense geological activity.
What is the oceanic- oceanic convergent boundary?
An oceanic-oceanic convergent boundary occurs when two oceanic tectonic plates collide, leading to one plate being subducted beneath the other. This subduction creates deep ocean trenches and can result in volcanic activity associated with island arcs. The intense pressure and heat from the subduction process can also lead to earthquakes. Notable examples include the Mariana Trench and the Aleutian Islands.
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 type of boundary forms when an oceanic plate is pushed under a continental plate?
A convergent boundary forms when an oceanic plate is pushed under a continental plate. This process, known as subduction, can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
Oceanic-continental convergent plate boundary.?
In an oceanic-continental convergent plate boundary, an oceanic plate is subducted beneath a continental plate due to differences in density. This process can lead to the formation of deep ocean trenches, volcanic arcs on the continental plate, and earthquakes. The subduction of the oceanic plate can also cause melting of rock, leading to the formation of magma that can erupt as volcanoes on the continental plate.
What happens when oceanic and continental plates collide?
When oceanic and continental plates collide, the oceanic plate is usually forced under the continental plate in a process called subduction. This can result in the formation of mountain ranges on the continental plate and can lead to the creation of volcanic arcs. The collision can also cause earthquakes and tsunamis.
What is the type of plate boundary where two plates move together causig one of the slabs of lithosphere to descend into the mantle beneath an overriding plate?
This type of plate boundary is called a convergent boundary or subduction zone. It occurs when two tectonic plates collide, with the denser oceanic plate being forced beneath the less dense continental plate. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding 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 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 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 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 is the difference between a convergent boundary between an oceanic plate and a continental plate and a convergent boundary between two continental plates?
A convergent boundary between two continental plates causes both plates to crumple to form fold mountains e.g. the HimalayasA convergent boundary between a continental and an oceanic causes one to rise above the other. Granite is less dense than basalt, so the continental plate rises above the oceanic plate. This also forms mountains, like the Andes.
What kind of plate boundary does subduction take place at?
Subduction takes place at a convergent plate boundary, where two tectonic plates collide and one plate is forced beneath the other into the Earth's mantle. This process is associated with the formation of deep ocean trenches and volcanic arcs.
What happens at an oceanic- oceanic convergent plate boundry?
At an oceanic-oceanic convergent plate boundary, two oceanic tectonic plates collide, leading to one plate being subducted beneath the other. This subduction creates a trench on the ocean floor and can result in volcanic island arcs, as the subducted plate melts and generates magma that rises to the surface. Earthquakes are also common in these areas due to the intense pressure and friction generated by the colliding plates. Ultimately, this dynamic process contributes to the recycling of oceanic crust and the formation of new geological features.
Sea floor is destroyed in which plate boundry?
The sea floor is destroyed in subduction zones, where one tectonic plate is pushed beneath another. This process is responsible for the destruction of oceanic crust and the formation of deep ocean trenches.
