Based on the arrows showing direction of plate movement in the diagram below, what type of plate boundary exists between the South American Plate and African Plate?

A
a subduction zone

B
a divergent boundary

C
a transform boundary

D
a convergent boundary

Answer:

a divergent boundary

Explanation:

a divergent boundary is when two plates pull away or separate, as you can clearly see the arrows are going in different directions.

The western margin of the African Plate creates a divergent boundary with the North American Plate to the north and the South American Plate to the south, forming the central and southern Mid-Atlantic Ridge. Therefore, option (B) is correct.

A diverging boundary, also known as a divergent plate boundary, in plate tectonics is a linear structure that exists between two tectonic plates that are moving apart. Rifts are initially created by divergent boundaries within continents, and they gradually develop into rift valleys.

Along mid-ocean oceanic ridges, the majority of divergent borders are found (although some are on land). The greatest geological feature on Earth, the mid-ocean ridge system is a massive undersea mountain range that spans 23% of the planet's surface and is 65,000 km long and around 1000 km broad.
