What happens when an oceanic plate collides with a continental plate and sinks?
When an oceanic plate collides with a continental plate, the denser oceanic plate is forced beneath the continental plate in a process called subduction. This creates a deep oceanic trench. As the oceanic plate sinks, it heats up, melts, and forms magma that rises to the surface, leading to volcanic activity.
What does the phrase 'the less buoyant plate is subducted' mean?
It means that a tectonic plate that is denser than the surrounding material is being forced beneath another tectonic plate at a convergent plate boundary. This process is known as subduction, where the denser plate sinks into the mantle due to gravitational forces.
What happends when an oceanic plate goes under a continental plate?
When an oceanic plate goes under a continental plate in a process called subduction, the oceanic plate is forced down into the mantle due to its higher density. This creates a subduction zone where the oceanic plate melts and forms magma, leading to volcanic activity. The continental plate is usually uplifted, creating mountain ranges.
What happens when an oceanic plate moves under a continental plate?
When an oceanic plate moves under a continental plate, a subduction zone is formed. The oceanic plate is forced down into the mantle, where it melts and creates magma. This magma can then rise to the surface, causing volcanic activity on the continental plate.
Which would subduct if a continental and oceanic plate were to collide with each other?
The oceanic plate would subduct beneath the continental plate. This is because oceanic plates are denser than continental plates due to their composition, so they are more likely to be forced beneath the less dense continental plate.

When an oceanic plate collides with a continental plate, the denser oceanic plate is forced beneath the continental plate in a process called subduction. This creates a deep oceanic trench. As the oceanic plate sinks, it heats up, melts, and forms magma that rises to the surface, leading to volcanic activity.
What forms when one oceanic plate is forced beneath another plate a rift valley an ocean basin an ocean ridge a subduction zone?
A subduction zone forms when one oceanic plate is forced beneath another plate. This process can lead to the formation of volcanic arcs, deep ocean trenches, and seismic activity.
How and why does an oceanic trench form?
An oceanic trench forms when one tectonic plate is forced beneath another in a process called subduction. This occurs at convergent plate boundaries where two plates collide. The denser oceanic plate is forced downward into the mantle, creating a deep trench.
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 forms when a continental plate collides with an oceanic plate?
it forms a trench
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.

One plate sinking beneath another?
Subduction
This type of boundary forms when two oceanic plates collide.?
convergent
What are the types of collisions that happen at convergent boundaries?
Subduction (where one plate is forced beneath another less dense plate - may occur at oceanic-oceanic and oceanic-continental boundaries), obduction (where oceanic plate is forced over a continental plate) and orogenesis where two continental plates collide and mountains are formed (e.g. the Himalayas).
Where is the oceanic crust sinking into mantle?
The oceanic crust sinks into the mantle at subduction zones, which are typically located where two tectonic plates meet. As one plate moves beneath another, the denser oceanic crust is forced down into the mantle, creating deep oceanic trenches. This process is one of the driving forces behind plate tectonics and the movement of Earth's lithosphere.
