| At the same time, the upwelling of mantle material at divergent boundaries creates mid-ocean ridges. |
|
| The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with the phenomenon known as hotspots. |
|
| At divergent boundaries, two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. |
|
| These structural regimes broadly relate to convergent boundaries, divergent boundaries, and transform boundaries, respectively, between tectonic plates. |
|
| Divergent boundaries within continents initially produce rifts which eventually become rift valleys. |
|
| Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill. |
|
| Divergent boundaries can create massive fault zones in the oceanic ridge system. |
