Convergent continental crust can lead to the formation of oceanic plates through a process called subduction. When two tectonic plates collide, the denser oceanic plate is forced beneath the less dense continental plate, creating a subduction zone. As the oceanic plate descends into the mantle, it can partially melt and contribute to volcanic activity on the continental crust. Over time, this process can lead to the creation of new oceanic crust as the material is recycled and reformed.

What two types of plates does convergent boundaries involve?
There are two types of crust on Earth: oceanic and continental. A convergent plate boundary can involve two plates of oceanic crust, two of continental crust, or one of each.
Why do convergent oceanic plates subduct but continental plates do not usually respond in this way?
Oceanic crust is denser than continental crust, dense enough to sink into the mantle. Continental crust is not dense enough to do this.
What are convertgent boundaries?
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
Which convergent boundary that does not have a subduction zone?
A convergent boundary that does not have a subduction zone is a continental-continental convergent boundary. At this type of boundary, two continental plates collide and crumple, leading to the formation of mountain ranges, such as the Himalayas. Since both plates are buoyant and primarily composed of continental crust, neither plate is forced beneath the other, unlike in oceanic-continental or oceanic-oceanic boundaries.
Why are continental volcanoes associated with oceanic continental convergent boundaries?
Continental volcanoes form at oceanic-continental convergent boundaries because as oceanic plates are subducted beneath continental plates, the subducted oceanic crust melts due to the high temperatures and pressures deep within the Earth. This molten rock then rises to the surface, resulting in volcanic eruptions on the continental plate.

Crust is destroyed near?
Crust is destroyed at the convergent plate boundaries in Earth. In between the oceanic and continental plates, the subduction of the denser oceanic crust takes place.
What two types of crust are involved at this type of convergent boundary?
The two types of Crust is the Continental Crust and the Oceanic Crust.
Why are continental volcanoes associated with oceanic continental convergent boundaries?
Continental volcanoes form at oceanic-continental convergent boundaries because as oceanic plates are subducted beneath continental plates, the subducted oceanic crust melts due to the high temperatures and pressures deep within the Earth. This molten rock then rises to the surface, resulting in volcanic eruptions on the continental plate.
How do the mountains that form along an oceanic oceanic convergent boundary differ from those associated with an oceanic continental convergent boundary?
the oceanic plates are denser than continental plates, therefore, when oceanic plates and continental plates converge, the oceanic will go under the continental plates. But when two oceanic converge either both will rise to form moutains, or both will sink and cause a trench.
Which plate boundary destroys crust?
Crust is destroyed at the convergent plate boundary. This is usually between the oceanic and continental plates. This is where subduction of the more dense crust occurs.
Why oceanic crust is always subducted underneath continental crust?
Oceanic crust is denser than continental crust, so when they collide, the denser oceanic crust is forced beneath the lighter continental crust in a process known as subduction. This subduction occurs at convergent plate boundaries where two plates are moving towards each other. The sinking oceanic crust can trigger volcanic activity and create mountain ranges on the continental crust.
What is the difference between continentalcrust and the oceanic?
Continental crust is thicker and less dense while oceanic crust is thinner and more dense, so essentially continental crust takes a higher position than oceanic crust. When oceanic and continental plates collide, oceanic plates slide underneath continental plates(if this makes what I said any clearer).
Do tectonic plates consist of continental or oceanic crust?
Tectonic plates consist of both continental and oceanic crust. The Earth's lithosphere is divided into several large and small plates that constantly move and interact with each other. Some plates are predominantly made up of continental crust, while others are mostly composed of oceanic crust.
What is layer has the oceanic and continental plates?
The crust.
