It is a process called ridge push.

Why do volcanoes occur near trenches?
Volcanoes are located often near trenches because when two tectonic plates collide at a convergent boundary, the denser plate slides under the other plate. As the denser plate bends, a deep depression known as a trench forms. At a trench, one plate moves downward into the mantle. As the plate moves farther downward into Earth's mantle, the rock is subjected to greater heat and pressure. As a result, the plate releases fluids, which causes surrounding rock to melt. This as you know is a volcano.
What force drives dense pieces of oceanic crust downward toward the mantle?
New crust is formed on the opposite end of the plate as it is pulled away from its neighbor
What is the downward movement into the asthenosphere of a lithospheric plate?
Subduction.
What Rock that is forced downward and is altered due to heat and pressure?
Ultimately gravity.A2. In a scree or talus, the rocks will fall to eventually come to rest. The driving force is gravity.In a stream, they will be borne easily in steeper streams but in a stream of shallow angle, their movement will be slight. Indeed their only movement may be in a flood. The material will become more worn down as it proceeds downstream. But the force moving the water is still gravity.
What is an earth plate?
An earth plate is a plate you equip to arceus to make its ground type moves.
What is the force that moves a cool dense plate deep into the mantle?
ridge push
What drives plate movement by pushing rock back into the mantle where it melts?
Well rifts do the pushing, but gravity does the downward motion causing the melting.
What do scientists believe is the force behind plate tectonics theory?
gravity slab pull

What is gravity's affect on plate movement?
One theory is that gravity pulls the old heavier ocean floor with more force than the newer lighter sea floor.
Can plate tectonics affect gravity waves?
In theory an earthquake moves enough matter quickly enough to create a gravity wave, but in practice, that gravity wave is much too weak for us to detect at our present level of technology.

What is the downward movement into the asthenosphere of a lithospheric plate?
Subduction.
What type of plate boundary is caused by a downward convection current in the mantel?
A destructive plate boundary.
What force drives the process of pulling dense pieces of oceanic crust downward towards the mantle?
New crust is formed on the opposite end of the plate as it is pulled away from its neighbor.
In which direction is the indo-australian plate moving?
The Indo-Australian plate moves Northeast as the Pacific Plate moves around it in a Northwest direction as if rotating.
What force causes rock to change into a different rock?
Heat, pressure, weather, gravity, plate tectonics--all play a part in the rock cycle.
