Answer:
Rises towards the crust
Explanation:
In the Earth's crust, movement of materials is as a result of thermal convection that is occurring within the earth's crust.
When thermal convection occurs, the warm, less dense material inside earth rises towards the crust , while the cool and denser material with sink towards the outer core.
This rising of warm, dense material and sinking of cool, denser material causes a shift in the tectonic plates and stimulates the release of a convection current.
