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
Convergent boundary with no subduction?
A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors. Continental plates are thicker and less dense than oceanic plates, and when they converge, they push up the area where the plates meet, forming mountain ranges (note that this is not the only, or even the predominant, method of mountain formation). The Himalayas are being formed as a result of a continental-continental boundary.
Why are continental plates less dense than oceanic plates kids answer?
Continental crust and continental crust are made of different types of rock. The rocks in the continental crust do not contain as many of the heavier elements as the ones in the oceanic crust do.

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.
Convergent boundary with no subduction?
A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.

Do tectonic plates consist of continental or oceanic crust?
They can be either continental or oceanic crust.
How are convergent plate margins characterized?
Convergent plate margins are characterized as collision zones between plates and may involve continental to continental crust, continental to oceanic crust, or oceanic to oceanic crust. Those that involve oceanic crust result in subduction of the more dense plate into the Earth's mantle. Continental to continental plate collisions result in uplift of the surface features and mountain building and the margin may eventually become welded together.
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.
Differences of the continental crust and oceanic crust?
Thickness - continental = much thickerDensity - oceanic crust is denser than continental, which is why the oceanic crust subducts under the continental at destructive plates boundaries.
How is continental lithosphere different from oceanic lithosphere?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
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).
What is layer has the oceanic and continental plates?
The crust.
