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.
Divergent boundaries that develop in the ocean lead to the creation of mountains and volcanoes, according to the National Geographic. This occurs because magma from deep within the Earth rises at the point of a divergent boundary and creates new crust. When a divergent boundary occurs on land, it leads to the formation of a valley known as a rift. One example of a divergent boundary that is occurring on land is the Great Rift Valley. This divergent boundary is pulling the continent of Africa in two different directions. Eventually, this particular boundary is going to cause the continent to break apart into two separate land masses.
