Yes, because otherwise, the plates, moved by the convection currents, won't move at all.
a convection current transfers heat within a fluid.

a convection current is the flow that transfers heat withen a fulid.
The transmission of heat requiring the movement of a liquid or a gas is called convection.
In a convection current, heat flows with the heated molecules as they move around in the liquid or gas. In a solid, the heat transfers via condition
heat rises and cold desends
A convection current is when hot air rises, and cool air fall, creating convection.~Britney, 7th
The heat comes from the outer core, which provides the heat.
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.
