|
convergence of oceanic crust
|
|
|
divergence of continental crust

Explanation:
Detailed explanation-1: -On land, rift valleys form where plates diverge. A good example of this is the East African rift valley. At transform boundaries, plates are sliding past each other horizontally in different directions.
Detailed explanation-2: -This developing rift zone is gradually separating the east part of the continent. The west side of the African major plate diverges from the North American plate. These divergent plate boundaries form the mid-oceanic ridges or rift valleys.
Detailed explanation-3: -The East African Rift Valley represents the spreading that is occurring at a diverging plate boundary. In the future, the rift valley will continue to spread and will ultimately become an ocean basin.
