What are 3 things continental-continental divergent boundaries form

Rift valley, fault, graben and mid oceanic ridge are the landform formed due to divergent plate boundary.

Explanation:

Plate boundary explains convergent or destructive, divergent or constructive and transform plate boundary across the world between different plates. African rift valley formed in the Africn continent which is major landform due to divergent plate boundary. Faault and graben also formed which means narrower than rift valley.
