slab pull
Tectonic plates are composed of the crust and upper mantle rock which is lighter than the more dense mantle. Rising and falling convection currents in the mantle cause imperceptibly slow movements in the plates (on the rate of fingernail growth). The source of the heat driving the convection currents comes from residual heat from the Earth's formative processes, pressure from gravity, and from radioactive decay of elements.there is also something called the slab-pull force. This occurs when a more dense oceanic plate subducts under a less dense plate and pulls the rest of the plate along. The subducting plate drives the downward-moving portion of convection currents.
The ultimate source of heat that drives plate tectonics is believed to be the Earth's internal heat from radioactive decay in the mantle. This heat causes convection currents in the mantle, which in turn drive the movement of the tectonic plates.
The energy source that drives the processes forming igneous and metamorphic rocks is primarily found within the Earth's interior. It originates from heat generated by radioactive decay in the mantle and core, which drives convection currents that bring hot molten material to the surface and causes interactions that lead to rock formation.
A mantle plume. These plumes are thought to be responsible for hotspot volcanism, where magma erupts through the Earth's crust in localized regions, such as the Hawaiian Islands. The source of mantle plumes is still debated among geologists.
Convection pushes tectonic plates around through the rise and sinking of heated liquid. Convection currents occur in the asthenosphere, and these currents contribute to the moving plates which are located just above.

The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.

The heat source for the convection currents in the mantle is primarily the heat leftover from Earth's formation and the heat produced by radioactive decay of elements within the mantle. The heat from the Sun does not directly drive mantle convection, although it does play a role in surface processes like weather and climate.
Bad grammar.
False.
The heat in the Earth's interior comes from two main sources: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust and the primordial heat left over from the formation of the Earth.
