Convection currents in the mantle create plate tectonics.

Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.

What role do convection currents play as you heat a pot of water?
The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
What causes Earth's plates to move?
A brief summary of this long answer can be found by viewing the related question. For more information please read on!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!For more information, please see the related link.
What role do plate tectonics play in physical geography?
nothing
What role does heat play in the rock cycle?
Heat energy from the sun causes water to change to a liquid to a gas
What role does convection play in precipitation?
Convectional precipitation occurs in hot, moist climates where the sun quickly heats the air. The heated air rises, and by afternoon clouds form and rain falls.
What role does friction play in plate motion?

Does gravity play a role in plate movement?
From what I know, Geologists have two main theories on why plates move. -The First idea is that at converging plate margins (constructive) as material moves up, the plates are pushed outwards -The second idea is that convection currents within the asthenosphere, (below the plates) which push plates along as if they were on wheels. These currents are formed as partially melted rocks rise because they are heated because it is hotter closer to the core and hotter materials rise. However, after rising for a while, the material cools and drops down again. This forms circular movements of rock which push the plates along. According to these theories, gravity doesn't but there might be another theory which says otherwise.
How does plate tectonics play a role in the formation and eruption and volcanoes?
Volcanoes and volcanic activity occurs at plate boundaries. Especially when one plate over rides another plate - convergent boundary. As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries.
Heat from the solid mantle is released through a process called?
Radiation. For more details. contact at saqibahmad81@yahoo.comanswer 2 Initially, the heat from the mantle will be carried by conduction to the upper layers, and eventually lost to the surface by radiation. Volcanoes may play a small part.
Can an earthquake be caused by temperature?
Not by temperature variations at Earth's surface, no. However, temperature variations in Earth's mantle play a role in plate tectonics, and so can affect earthquake activity.
Does convection play a part in weather?
Yes.

How do plate tectonics move?
Tectonic plates are segments of the Earth's lithosphere, the hard rocky outer shell composed of the crust and the uppermost mantle. This shell is divided by lines of faults, ridges of plate creation, and zones of plate destruction. All in all, there are roughly 30 tectonic plates which cover the entire surface of the planet. Plates can be composed of oceanic crust, continental crust, or a combination of both. Plate movements occur because the layer of Earth directly below the lithosphere, the asthenosphere, is hot enough, and under enough lithostatic pressure to prevent its melting, that it can deform without fracture. And although convection of heat does play a role in the movement of lithospheric plates, the convection currents themselves may be caused by gravity, which induces the sinking of older dense slabs of oceanic crust at subduction zones (a process known as 'slab pull'). The energy driving all of these processes is heat from the interior of the Earth derived from radioactive decay and residual heat from Earth's formation, and gravity which results in slab pull and push.
