Answer:
Convection
Step-by-step explanation:
Hello,
Mantle convection is driven by three main processes: heat loss from the core, internal heating from radioactive decay and cooling from above (sinking of lithospheric slabs). Mantle convection is responsible for the movements of lithospheric plates, earthquakes, magmatism, surface volcanic activity, and, indeed, most of the geological and tectonic processes manifested in the crust due to the action of the transferred heat.
Best regards.
