The movement of Earth materials through the mantle and toward the crust due to heat transfer is an example of convection.

Convection is one of the methods of heat transfer where heat moves through a liquid medium.

According to this question, Earth materials move through the mantle towards the crust. This slow motion carries materials such as silicate etc from the interior to the exterior part of the Earth via convection currents.

Therefore, the movement of Earth materials through the mantle and toward the crust due to heat transfer is an example of convection.
