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.

When the heat source is removed from a fluid, convection currents in the fluid will eventually slow down and dissipate as the fluid cools. The fluid will then return to a more quiescent state with less movement and mixing.
False.
False.
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 heat makes it rise up
the heat in the core raises and heat raises to a cold spot. so the convection currents raises to the surface of the earth.
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.
The Sun.
No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
