Explanation:
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. As the magma are introduce the opposing plates separates further . The basaltic magma introduced through the oceanic ridges forms the new oceanic crust. As we move away from the oceanic ridge the rocks gets older . The oceanic ridge where the basaltic magma erupt depict the youngest rocks.
