A divergent boundary is one of the three types of plate boundaries, and occurs when two plates separate resulting in ridges. The option is Ridges.
What are the three types of boundaries?
I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
This is a Collision area between two plates.
- Two oceanic plates might collide,
- One oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.
Ridges are formed when divergent movements occur between plates. For instance, the mid-ocean ridge was created by divergent boundaries. The Atlantic ridge, the Chilean ridge, the East Pacific Ridge, and the Indian ridges.
The correct option is Ridges.
