Answer:
True
Step-by-step explanation:
This is because as mantle convection slowly creep molecules that are warmer into the motion or movement in mantle cells, the cooler part of the rock move out of the mantle in the earth, convection currents continue to flow that carries heat into the mantle core. The mantle remain solid, the convection current that carry heat to the core, cause deformation of geologic structures on the mantle.
