-A divergent boundary also called the divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges.
-Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys.They are constructive boundaries. Convergent boundaries on the other hand are areas where plates move toward each other and collide.
