What are the examples of divergent boundary?

Examples of a divergent boundary would be a mid-ocean ridge. Two plates are pulling apart from each other. If you have heard before, the magma from the asthenosphere find a way to get out through the crack of the diverging plates and makes new land. Another type of devergent boundary would be a fissure. It is a long linear crack made by the plates moving apart. I think maybe another one would probably be a volcano, but I am not sure.
