Answer 1

C.

Convection occurs due to the different relative densities of materials.

Step-by-step explanation:

Heating within the Earth lowers the density of parts of the Earth's mantle. In areas where these lower-density materials lie beneath cooler, higher-density materials, an unstable condition develops. To stabilize this condition, the cooler, higher-density materials flow downward while the hotter, lower-density materials flow upward. This vertical flow of material is called convection.
