Hot mantle rock moving toward the surface partially melts because the pressure is reduced. The magma produced moves upward into cracks in the crust and is extruded onto the sea floor.

What are the long-term geological consequences of divergent plate boundaries?

Select one of the following options:
  • A.

    Divergent boundaries cause immediate and rapid formation of mountain ranges on continental plates.

  • B.

    Divergent boundaries result in the permanent stabilization of oceanic plates, preventing further geological activity.

  • C.

    Divergent plate boundaries lead to the formation of new ocean basins by gradually widening and creating mid-ocean ridges, eventually causing continental breakup as seen in the separation of Africa and South America.

  • D.

    Divergent boundaries primarily lead to the formation of volcanic arcs and deep-sea trenches.
