Rift valley's veins stretch their length through the entire surface, like Benue, part of the broader West and Central African Rift System. Tectonic plates are continually changing in fault zones, subducting beneath each other, colliding at convergent plate boundaries, and tearing apart at divergent plate boundaries.
