Divergent boundary is where tectonic plate move apart from each other. Divergent boundary is mostly prevalent in the oceanic crust. The opposing plate tends to move apart from each other.
On the oceanic crust plates move apart from each other causing an upwelling of magma from the aesthenosphere. This magmatic material is introduced through the oceanic ridges.
