New crust forms as plates move over hotspots. Eventually The Great Rift Valley will fill with water and become a sea. 2 Schematic Representation Of The Three Types Of Plate Boundaries Download Scientific Diagram System is a giant undersea mountain range and is the largest. . Most divergent boundaries are located along mid-ocean oceanic ridges although some are on land. The Great Rift Valley in Africa and the Mid-Ocean Ridge were all created by this boundary. At a divergent boundary two plates move apart and new magma rises to the surface creating a new crust. Which of the following boundaries is a divergent boundary. Divergent boundaries exist where tectonic plates move apart from each other. When we speak of divergent boundary we also refer to the constructive. Unlike convergent boundaries divergence occurs between only. There are two types of divergent boundaries categorized by where they occur. The conv...
