Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
The place where two plates move apart, or diverge, is called a divergent boundary (dy vur junt). Most divergent boundaries occur along the mid-ocean ridges where sea-floor spreading occurs. Divergent Boundaries. Divergent boundaries also occur on land. When a divergent boundary develops on land, two of Earthâs plates slide apart. A deep valley called a rift valley forms along the divergent boundary. For example, the Great Rift Valley in East Africa marks a deep crack in the African continent.
