Answer:

C. When the oceanic lithosphere, which is more dense, sinks and pulls the plate with it

Explanation:

Slab pull and other mechanisms are responsible for the motion of plates. Every tectonic plate is driven by mantle convection.

  • Convection is a form of heat transfer in fluids.
  • It is as a result of differences in density and temperature values.
  • The oceanic crust is denser and colder.
  • As hot magma from deep within the subsurface rises and move through cracks, the oceanic lithosphere is drawn down and deeper.
  • This cycling between the cold lithosphere and hot rising plumes provides the mechanism that drives plate motion.
