Why is the oceanic plate subducted when an oceanic plate collides with a continental plate?
The Oceanic plate is subducted under the Continental plate because oceanic crust is much more dense than continental crust. The average density of the oceanic crust is 3g/cm^3 while the average density of continental crust is 2.7g/cm^3.
Do continental plates move faster than oceanic plates?
No, oceanic plates move faster than continental plates. This is due to the density of the oceanic plates (basalt is denser). For example, the fastest moving plates are the Pacific plate, Cocos plate, and Nazca plate. All oceanic.
Is the arabian plate continental or oceanic?
oceanic plate
When a continental plate and an oceanic plate collide why does the oceanic plate sink below the continental plate?
It's because the oceanic plate is more dense than the continental plate.
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 happens when a plate gets subducted?
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.
At a convergent plate boundary between a continental and an oceanic plate which plate will be subdued down into the mantle?
The oceanic plate will be subdued down into the mantle because it is denser. Or has more density*smiles* Hope I helped.
Plate with oceanic crust sinking under another plate with oceanic crust?
When two oceanic plates or two plates both containing oceanic crust collide or converge, the convergent boundary will form a trench. The plate which has the higher density will plunge beneath the other plate forming a trench.
Do continental plates move faster than oceanic plates?
No, oceanic plates move faster than continental plates. This is due to the density of the oceanic plates (basalt is denser). For example, the fastest moving plates are the Pacific plate, Cocos plate, and Nazca plate. All oceanic.
Is the Pacific plate and oceanic plate or continental plate?
It is oceanic
Is the antarctic plate an oceanic or continental plate?
The Antarctic plate is Oceanic.
Is the arabian plate continental or oceanic?
oceanic plate
What happens to an oceanic plate as it pushes against a continental plate and sinks?
The oceanic plate sinks into the mantle where it melts. This is replaced by new oceanic plate at the mid-oceanic ridge.
When a continental plate and an oceanic plate collide why does the oceanic plate sink below the continental plate?
It's because the oceanic plate is more dense than the continental plate.
What is a Earth crust?
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
What is a continental crust?
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
