During convection, hot material rises due to its lower density, creating a current that transfers heat from the hot material to cooler material. This process then causes the cooler material to sink and cycle back towards the heat source, creating a continuous convection current.
If the interior of the Earth cools down, the convection currents in the mantle will gradually slow down and eventually stop. This will result in decreased heat transfer and mantle movement, potentially leading to a decrease in tectonic plate movement and volcanic activity over time.
It's known as a convection current not a conduction current :)
How does a convection current move rock
The motion created when heated material rises, cools, and then sinks is called convection. This process is driven by differences in temperature and density, with warmer, less dense material rising and cooler, denser material sinking. Convection is a key process in transferring heat and energy within the Earth's mantle and atmosphere.
Cool enough to increase in density and sink.
During convection, hot material rises due to its lower density, creating a convection current. As the material moves to the side, it cools down, becomes denser, and eventually sinks, completing the circular pattern of convection. This process is driven by temperature differences within the fluid.
Convection Current
the convection currents will stop
warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
... move to the bottom of the fluid

This process is known as convection. Warm material rises because it is less dense than cold material, creating a convection current. As the warm material rises and the cold material sinks, heat is transferred through the movement of the material.
