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 it called when one plate is pushed under another plate as the collide?
subduction boundary!!!
What geological features are caused by a subduction?
When a plate is subducted under another the geological feature depends what type of plate boundary it is. If it is two oceanic plates then the subduction causes Island Arcs to be formed as well as a trenches. When a oceanic plate is subducted under a continental plate then a trench is again formed just off the shore of the continental plate and fold mountains are created as the continental plate is forced upwards and the friction melts the oceanic plate into magma which then rises (as it is less dense than surrounding magma) and forms volcanos.
When a more dense oceanic plate sinks under continental plate?
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
Which rock is denser continental or oceanic rock?
The average continental rock is less dense than the average oceanic rock. This is why when an oceanic and continental plate collide, the continental plate does not get subducted. There are varyations within the continental plates however, with some rocks being muck more dense and some being much less dense than the average.
What plate boundary was the Chilean earthquake on?
The earthquake occurred at a convergent boundary between the Nazca and South American plates which are converging at a rate of approximately 80mm / year. The dense oceanic crust of the Nazca plate is being forced under or subducted beneath the less dense continental crust of the South American Plate.
Why is an oceanic plate always subducted but not a continental plate?
Continental plates are lighter (less dense) than oceanic plates.
Why is oceanic lithosphere subducted during and oceanic continental collision where as the continental plate is not?
the oceanic plate is less bouyant so it slides under the continental plate

subduction boundary!!!
How can matter be more or less buoyant?
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.

Does less ballast makes an object less buoyant?
No, the opposite.
By expanding and contracting their swim bladders fish can change their level in water How does this enable fish to become more or less buoyant?
(a) This helps them become more or less buoyant, because if they release the gas then they will sink making it more buoyant by getting air from the surface or from other bubbles it makes them less buoyant, making them float.

Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
How do plates form?
In the proses of a subduction, one plate (normally an oceanic plate) is formed beneath another into the solid but fluid mantle below. When the subducted plate is thicker, less dense continental plate, it resists being pushed into the thicker rock, and pushes upward on the overlying plate. This buckles the overlying crust and increases its elevation. It should not be noted that mountains are "built" almost as slowly as they are eroded the proses taking place over tens of millions of years.
If you climb a high mountain the buoyant force exerted on you by the atmosphere?
It is less.
