This is a complex question and is a subject of continuing ongoing scientific research. A summary of some of the hypothesised causal mechanisms of plate movement (based on scientists current understanding of the process) is given below:
The primary source of energy for the motion of the lithospheric plates is dissipation of energy from the earth in the form of heat transfer. This heat transfer causes convection within the mantle and this convecting mantle material is hypothesised to exert a drag force on the base of the lithosphere. This is known as Basal Drag and was thought to be an important driver of tectonic plate motion until recently when advances in geophysical imaging techniques (specifically 3D seismic tomography) allowed geophysicists to form a more detailed model of the structure of the mantle but were unable to locate the necessary large scale convections structures. Further to this, geophysicists no longer believe that the asthenosphere has the necessary stiffness or rigidity to cause sufficient friction on the base of the lithosphere to be a significant driver of plate motion.
Gravity is also believed to play a role in the driving of plate motions, both at mid-ocean-ridges (MOR) and at subduction zones. Both these mechanisms are also linked to the dissipation of heat and convection in that they are reliant on variations in the buoyancy of the lithosphere as temperature changes occur as described below:
When hot (and so low density, buoyant) mantle material rises at an MOR, it is intruded into the pre-existing oceanic lithosphere as well as extruded at the upper surface. This newly intruded material is at a high temperature and cools relatively slowly. As such the newly formed oceanic lithosphere is buoyant and rises relative to the older cooler oceanic lithosphere further from the MOR. Even though this younger lithospheric crust is buoyant it is still significantly denser than the underlying upwelling hot mantle material and so "slides" down away from the crest in a process known as gravitational sliding. This is considered a secondary driving force as it only acts in close proximity to the ridge and does not transmit load into the surrounding lithosphere (it does not "push" the lithosphere away from the ridge, it is instead dragged - the tectonic regime is tensile, not compressive).
Another more significant gravitational driving force of plate motion is that caused by the old, cool and so low buoyancy oceanic crust that sinks back into the mantle at subduction zones and acts to drag the attached oceanic lithosphere towards the plate boundary. This is known as slab pull and is thought to be a significant driver of plate motions as it has been observed that tectonic plates with subduction boundaries tend to move with a higher velocity than those without. Subducting oceanic slabs also promote another driving force of plate motion known as trench or slab suction. This is a process where the movement of the downgoing slab promotes flow in the nearby mantle. This flowing mantle material is thought to exert a traction both on the downgoing slab and the overlying non subducting slab, pulling them both towards the subduction zone.
It should be noted that not all plates have significant subduction boundaries and yet still undergo plate movements so it is possible that a combination of all these mechanisms influences plate movement (as well as the possibility that there is some as yet undiscovered driving force that has a significant role).
The above is a simple summary of a complex topic and as has been stated the causal mechanisms that drive the motions of tectonic plates are not fully understood and as such the reader should remember that this is a current and active area of research in geophysics and so the hypotheses summarised above may be accepted, rejected or modified over time!

Convection within the Earth's mantle carries heat to the lower crust. This pushes upward and also liquefies rock into magma, which can move between layers and even upward to the surface. The plates are pushed very slowly either away from, into, or past each other. In many cases, plates will be subducted below other plates when they are pushed together, while new crust is formed where they are pushed apart.
The asthenosphere that is made up of hot, liquid rock. The hot liquid and gases flow outward from the inner part of the asthenosphere. This flow of hot, liquid rock below the lithosphere causes the plates to move.
Convection Currents
It iz what it iz
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
The plates move
The energy from the core of the earth causes currents in the molten layers, the way there are currents in the ocean. These currents are what causes the Tectonic Plates to move along the surface of the earth.
the continental plates are caused when silicon,silica and dioxid combined together making the plates split and then it causes the plates to move.
Lower mantle is the surface on which the lithospheric plates move around earths surface.
Convection in the earth's mantle.
what causes the earths tectonic plates to move
the tectonic platesthe tectonic plates can be move to be far and near to each other
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
because they are pushing against one another and so it causes fricton. when there is fricton the plates move and create a earth quake and or creves
The plates rub together causing the rocks to move and it causes the ground to shake forming an earthquake. The more the plates move, the bigger the earthquake number.
because of the plates in earth shift fast and the force causes the earth to shake.
Sometimes it causes earthquakes, as well as when earths plates move in opposite directions. But yes, volcanoes are also formed when these plates move out of place or away from each other, for example Hawaii. That is an example of plates sliding through the ocean which causes islands.
The movement of the Earth's plates is known as plate tectonics. Geologists think the plates move due to a build up of extreme heat in the Earth's crust.
Well, when earths plates move away from each other that's when it happens but move well then NO!
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
yes
