The process that brings heat from the lower mantle toward the crust is **4. convection**.
Convection involves the movement of heat through fluids (which include liquids and gases) where hotter, less dense material rises, while cooler, denser material sinks. This process plays a significant role in the transfer of heat from the Earth's mantle to the crust.
