Answer:

A. Cooler material in the mantel moves down, and warmer material in the mantle moves up.

Explanation:

Heat always rises due to being lighter because the atoms in the material is spread out, while cold goes down due to being heavier because the atoms in the material is more compact.

Mantle convection is a slow creep of the earth's mantle due to the convective current that takes the heat from the earth's interior to the surface.

  • The convective current coming from the mantle is known to be the driving force for the drifting and collision of continental plates.
  • These correct comes from the mid Atlantic ridges and may also come to form the mantle plumes which may cause surface volcanism.

Hence option A is correct, warmer material rising up.
