Answer:
Tectonic plates.
Step-by-step explanation:
At the divergent boundaries, two plates move away from each other and the space produced by this spacing is filled by a new magmatic crust material. Thus, the divergent limit is constructive, since it allows the expansion of the ocean floor and the consequent formation of a new lithosphere.
According to this concept, we can say that the geographical features that are associated with a divergent boundary are the tectonic plates.
